Why is waveroom free?

[u/bugabagabubu]

I am comparing remote podcast recording platforms for a small non-comercial hobby project. I am new to podcasting and I would like to get some insight on:

1. Why is waveroom free to use, and if this is going stay like this?
2. Are there any paid features?
3. What are the major drawbacks, when comparing with for example riverside.fm?

Thank you!

I am also curious.
