Usually I wouldn't expect anything to happen to a big company like this, but oof...this is so much worse than the title makes it sound. If they leave something like this in their store, then all user trust will be gone.
I'll bet there's also a good number of developers at Anthropic itself who are now surprised to learn that every api token etc. that may have appeared in a Claude Code bash command is now leaked to a third party. Whoever can gain access to this telemetry server is sure to find a lot of valuable stuff in there.
