Yup, and I could do $5/month, perhaps more if they really seemed to need it. I don’t know if there are 8-9M, but maybe.
They really should be working on improving their revenue streams. I think they should work on privacy-friendly transactions, like a Mozilla Pay where I put money into some kind of bucket, then purchases are paid out of that bucket. The system would work on something like GNU Taler, and they’d take a small cut for money going into and out of the system (or transactions within the system). I could use those funds to pay for online services, avoiding ads, tips to people online, or Mozilla services.
