You need to test yourself.
Many paysite owners who tried the "lower the prices" experiment realized that they made more money with higher prices, and went back.
This is not a new idea btw, paysite owners were already trying it 10-15 years ago
While at it, a few other things most paysites tried, failed, and reverted from them:
- "Let's remove downloads and make the site streaming only"
- "Let's sell the updates individually rather than memberships"
- "Let's sell free memberships"
All of these things work for SOME sites built around those concepts. But for most, they fail.
