Vlad A lot of people do see Bypass Paywalls as their most important extension.
E.g. the mozilla extensions site https://addons.mozilla.org/en-GB/firefox/addon/bypass-paywalls-clean/ shows 144k users and 4.8 stars. It doesn't appear in Mozilla's most popular extensions list for some reason but those stats would appear to put it around 30th in user count and top 10-15 in rating - quite an achievement for an extension which only came out a couple years ago (the extensions with more users presumably racked them up back when Firefox was more popular) and which comes in multiple versions (the linked one doesn't request permissions for all sites - there is another which allows custom sites) and is often sideloaded. There is also a chrome version, which needs to be sideloaded, but is likely to have an additional order of magnitude more users.
See these recent posts in reddit r/ios (hardly a bastion of paywall blocking types, you would expect) and - by comparison r/ios posts like about extension support in general only get 5-15 votes.
