Google has everything that they do listed in their Privacy Policy, you may not like it but its all in there. A small malicious company might not care so much indeed.

True, however, if it turns out (ie gets leaked or proven) that this company doesn’t follow their Privacy Policy, it is a very bad look for them and subjects them to fines (or other punishments) from DPA’s.

Check the extension’s privacy policy (usually linked on the installation page). If there’s anything you don’t like, don’t use the extension :)
