He also has always asked and worked with his community for what they want. I've been on Sync since 2014 and have nothing tying me to it, but the fact when I had issues he responded personally and got it fixed, really made an impression. I remember back when he took a break for a couple years to work on his degree, he came back swinging hard on this project.

I'll gladly leave the app if it ever doesn't have my interests in mind. However that time has not yet arrived.

These people aren't arguing in good faith. They're just stretching for any strawman they can to justify the fact that they don't want to spend money or see ads. In other words "Do a bunch of work for me to benefit from for free".

Sync has been good to me for the better part of a decade and after a little while on the free app I will most likely end up paying. He has earned it.
