I'm pretty close to reaching their free tier's cap on outgoing bandwidth. They only give you 100 GB.

To buy another 100 GB I would have to pay $20 per month (4x as expensive).

Also I don't feel comfortable basing my entire business on Netlify. My blog and course landing pages are how I earn a living. It's the same reason why I don't use GitHub pages. I just don't like the idea of having to adhere to their TOS (even if I'm not doing anything wrong) and also be limited to their free tier's traffic constraints.

I'm sure they are a good company and I wish nothing but the best for them but I just don't see them as a good fit for me given the above.
