You need to differentiate between BB Personal Backup and BB B2 service which is more like something you suggested. But these days I just use rsync.net + Wasabi + Kopia + rclone.
Particularly given you never address the commenter's point, which is that your pricing is pretty expensive?
"Price high, low volume" is certainly a valid pricing strategy, but you have no right to be snarky when people say you're priced high.
The fact that people are consistently describing you as overpried means your marketing really isn't showing the corresponding value to them.
