This is why I only run open source extensions that I can actually audit. uBlock Origin, SponsorBlock, the kind of tools where the code is available and the developer isn't anonymous. The Chrome Web Store is basically unregulated and Google doesn't care as long as they get their cut. Open source at least gives you a chance to see what you're installing before it starts exfiltrating your data to some server in a country you've never heard of.
