Also my experience differs more broadly, I use browser extensions quite a bit, e.g. for ad blocking and password management. Afaik Honey was basically a browser extension and was bought by Paypal for $4B.
Now: You can no longer create new paid extensions or in-app items. This began as a temporary restriction in March 2020 due to the COVID-19 situation. This change is now made permanent. December 1, 2020: Free trials are disabled. The "Try Now" button in CWS will no longer be visible, and in-app free trial requests will result in an error. February 1, 2021: Your existing items and in-app purchases can no longer charge money with Chrome Web Store payments. You can still query license information for previously paid purchases and subscriptions. (The licensing API will accurately reflect the status of active subscriptions, but these subscriptions won’t auto-renew.) At some future time: The licensing API will no longer allow you to determine license status for your users.
I have the whole thing in my inbox if anyone is interested
