I suspect this is not a popular opinion, but Google's AGPL policy reads like FUD to me. From the first paragraph:

"...extremely difficult for Google to comply with..."

and

"...presents a huge risk to Google..."

and later in the document is the best part:

"This viral effect requires that the complete corresponding source code...".

All from a company which built itself on GPL software. This reminds me of Steve Ballmer ranting about Linux being a virus 20 years ago.

More:

"Do not install AGPL-licensed programs on your workstation, Google-issued laptop, or Google-issued phone without explicit authorization from the Open Source Programs Office."

Assuming Google follows its own policy, this just creates a hassle for its employees. Worse, Google making this public sends a strong anti-AGPL message to other companies. I'd bet $10 RStudio server (AGPL) is installed somewhere at Google (perhaps the commercial version). But other organizations with less sophisticated legal departments might just ban RStudio completely following Google's lead. I would not call Google irresponsible here, but I think it could act more responsibly.
