I assumed it was a Patreon because of the name, but its still a for profit company asking their customers for donations in the form of a monthly subscription so they can sell you more games. You don't get anything tangible out of it, just a private Discord and a badge on your name.
Its skeezy no matter how you spin it.
The day I have to watch ads is the same day I stop youtube. So far ad blocks seem to work well for now and I'm more than willing to spend hours getting them working if needed.
