Anthropic’s PR nightmare, Matthew Berman’s outburst, and AI usage explosion

23 avril 2026 à 22:12
The Anthropic Flywheel
Anthropic has spent the last year turning Claude into the darling of power coders just as AI usage has exploded across companies, workflows, and entire industries, pushing demand for agentic coding tools to unprecedented levels. In this environment of runaway adoption, a brutal miscalculation on compute and capacity is now blowing Anthropic’s strategy up in public. In a rare, sharply critical video, AI YouTuber Matthew Berman explains how opaque quotas, shifting policies, and confusing restrictions are undermining Anthropic’s once brilliant flywheel and handing OpenAI an effortless PR win. In this post, I summarize his critique, explain why I stopped trusting Anthropic for professional work a while back, and outline why building provider-agnostic agents is the only sane strategy in this unstable industry.

Azure migrate readiness overview
Azure Migrate, Microsoft's cloud migration hub, gained a new capability in April 2026: automated, agentless discovery and assessment of SMB and NFS file shares hosted on Windows and Linux servers. The feature extends Azure Migrate's existing workload coverage — which already included servers, databases, and web apps — to file shares. It recommends which of Microsoft's two Azure Files storage tiers is appropriate for each share and estimates monthly costs. Previously, file share migration planning relied on manual scripts or spreadsheets. This article explains how the feature works, what you need to use it, and where its limitations lie.

Entra now supports bidirectional scim provisioning
Microsoft introduced new SCIM 2.0 APIs for Microsoft Entra. The APIs now support bidirectional provisioning, which allows external identity systems to provision users and groups directly into Entra. SCIM (System for Cross-domain Identity Management) is an open internet standard that defines a common HTTP-based protocol for managing user accounts across different systems. Previously, Entra could only push user data to other applications via SCIM. Now, it also accepts incoming SCIM requests. The APIs follow a consumption-based pricing model, require an Azure subscription, and are generally available in the Microsoft public cloud.

Claude haiku is getting feedback from rubber duck in github copilot cli
GitHub Copilot CLI—GitHub's AI assistant for the terminal—introduced an experimental feature called Rubber Duck that pairs your primary AI model with an independent reviewer from a completely different AI vendor. The goal is to catch early planning mistakes before they compound into harder-to-fix downstream errors, a known weakness of single-model AI agents. In performance testing on real-world coding problems, combining Claude Sonnet with Rubber Duck closed 74.7% of the performance gap between Sonnet and the more capable Opus tier.

Mail-Advanced.ReadWrite permissions required to change sensitive email properties in Exchange Online via Graph API

Mail-Advanced.ReadWrite allows you to modify sensitive properties in Exchange Online
Microsoft announced a breaking change to the Microsoft Graph API affecting Exchange Online: from December 31, 2026, applications that modify sensitive email properties -- such as the subject, body, or recipients -- on delivered messages must hold elevated Mail-Advanced.ReadWrite permissions. Until now, the standard Mail.ReadWrite permission was sufficient for these operations. The new permissions require explicit approval from the tenant administrator ("admin consent"). If you operate Microsoft 365 and have custom applications or third-party tools that interact with email via the Graph API, you need to audit and potentially update these apps before the enforcement date.

Windows updates in Intune vs. SCCM patch management—April Fools and human hallucinations

Windows updates in Intune vs. SCCM patch management
On April 1, Microsoft published a TechCommunity blog post explaining how Windows Update management in Intune differs from Configuration Manager (still widely known as SCCM). A Techzine author read the post as an announcement of upcoming changes and reported that "patch behavior is set to change significantly for Microsoft Intune." That framing is a human hallucination, as Microsoft's post does not announce any changes.
