Isn't this precisely the pattern of behavior that gets you sued for anti-competitive practices?

This is exactly the same what Google does when it tries to prevent alternative Youtube clients by fiddling with the page design on purpose.

Nobody is claiming anticompetitive there

What?

Seriously, not at all. Anti-competitive practices is when you go out of your way to use legal agreements or practices, in an illegal way (i.e. from the starting point of a monopoly), to deliberately restrict the ability to use competition.

Openclaw is not a competitor with Claude. Anti-competitive practices would only occur here if Anthropic used some technique to prevent people from using Claude alternatives (i.e. if you install Claude Code, all other AI agents are forcibly disabled on your system).
