I agree. Unfortunately OAuth is impractical for this project, as it requires registering your application with Google.
Instead I've done my best to make clear how it works[0][1] and what is stored[2].
As mentioned in a sibling comment Google does not have a good track record with similar projects. AFAIK the only project that provides similar functionality is youtube-dl[3], which works the same way.
Important to note is that this functionality is optional; you do not need to log in with Google to store subscriptions or preferences. The main benefit currently is that it will automatically sync subscriptions with YouTube, otherwise I would recommend creating a new account on Invidious and then importing subscriptions from YouTube.
