It is a security feature. In a corporate environment, you generally don't want users installing their own software. If it's a remote access thing from a personal device, you still generally want to be able to establish some kind of baseline. I don't like Chrome - not even a little bit - but I will admit that they have a pretty damn good security track record. I'd rather my remote users be on there than some crusty Firefox installation with 40 extensions. Organizations have the right to make these decisions when they are the ones that own the data. For example, when I was still in that world, we required personal phones to be encrypted to access corporate email. This was when a lot of people would still walk around with devices without a pin. People complained, but it was non-negotiable.

Literally the only reason they can argue Chrome is more secure than Firefox in that kind of setting is because they can Google can push Google Chrome profiles via Google Workspaces but they’ve never working with Mozilla to create an interop for Firefox.

When Microsoft did this with Windows, AD, and Internet Explore, it was deemed a breach of anti-trust laws. The question is whether such laws apply to Google given they don’t have a monopoly in the identity services domain.

If you’d asked me 5 years ago, I’d have said “no way”, but recent judgements with Apple and their App Store lead me to think there is still hope. Regardless of how remote that might be.
