I support 35 non-profits with 4 Appwrite self-hosted instances. I fully support the idea of you guys charging for the work you put into Appwrite, as it is genuinely an incredible application. in fact, my very first flirt with Appwrite was my paid account for about 2 years. I do this all on the side and don't charge for database-related costs because of how easy and simple Appwrite has made it for my team and my clients.
the whole point of going self-hosted was that I could completely and independently support my entire infrastructure. now, a feature that I used to have full access and control over is now completely blocked behind a price that I can't see until I wait for an email response from a salesperson who likely does not have my best interest at heart. the whole reason I use so much free and open source software is control, privacy, and accountability being under one roof that I command, mostly for ease of my clients.
I do fully admit to paying some Enterprise licenses, just because there is no real foss resource that exists for me to replace it with. I also freely admit that I use resources that operate on a "freemium" basis. however, I try not to associate with businesses that take away features that were previously free and add them to paid plans, particularly when the paid plan has a nebulous cost.
