I think this is the most important takeaway from this thread and at some point, this will end up biting Google and Anthropic back.
OpenAI seems to have realized this and is actively trying to do the opposite. They welcomed OpenCode the same day Anthropic banned them, X is full of tweets of people saying codex $20 plan is more generous than Anthropic's $200 etc.
If you told me this story a year ago without naming companies, I would tell you it's OpenAI banning people and Google burning cash to win the race.
And it's not like their models are winning any awards in the community either.
