Yeah, you're not wrong that the article kinda sets itself up for the "lookit our recommended VPNs" pitch.
There's no way Microsoft would purposefully disable VPNs from working. I can guarantee that they require VPNs for thousands of roles in the company, let alone breaking it for government agencies that require VPNs, etc.
It is good to know that a specific update can break something ahead of time, though. Then at least you can avoid it.
