I don't mind to pay for services, I don't mind to pay for extra's as long as the money goes to the people doing the work and the people doing the work increase or maintain the user experience of said service.
The whole "you just want free stuff" people were shouting on Reddit is a bunch of balony.
Hosting costs money
Infrastructure costs money
Developing costs money
Maintenance costs money
All the above also costs time.
So of course it is okay for people to donate or have some monetization possibilities to keep the lights on and getting paid for the work they do so they can make a full time living from it or use it as a part time gig.
But there is still a difference size rift between the above and trying to monetize every single thing from your platform/user base just because of greed.
