DeArrow developer here

To clarify on what it happening, the extension was free for everyone while it was in beta, but as originally described on the website and install page, there is now a soft paywall for new users only. Those beta users also have a license key that they are encouraged to share with others if they would like :)

I understand you may not want to use this at all as a principal, which is fine, but I’ll explain the different things I’ve done to make this better.

• The extension and server source code are FOSS and self hostable
• The database is public and downloadable as with my other extension SponorBlock (https://sponsor.ajay.app/database)
• License keys are encouraged to be shared
• There is an option to request free access
• The payment option is one time forever

I understand if you still don’t want to use it though :)

Also if you want, here is a key :P FVE2Q-a3442
