If you think it should cost less because of N reasons -- self host it. There's an option for that vs. other solutions.

They don't need to justify their cost to you, ever, but especially when it's open sourced with an option to self host.

Correct. I'm just *wondering* why they choose that price. I don't want them to change it and they have every right to not talk about it.

I selfhost a lot of stuff. I don't understand why people think this is an attack.
