As a software engineer I find it miraculous the amount of people that whine about somebody wanting to get paid for putting weeks, months, and years of their life into a product 100s of thousands of people CHOOSE to use.
The idea is essentially debrid services download the content of a torrent, and once one user has requested them, its stored and available for all other users to download, so no more dealing with Torrents with 0 seeders, at the speed of top grade file hosting services.

You can get unlucky on the odd occasion, theirs some torrents out there where the actual video file format isn't friendly with streaming, but RealDebrid itself has been 100% reliable, for me anyway. If your using stremio their are settings you can change to increase the cache size, or you can play around with using a different video player within stremio, but in general the default settings should do the job.
