We're reaching the end of an era wherein billions of dollars of investor money was shovelled into tech startups to build large user-bases, and now those companies (now monoliths) are beginning to constrict their user-bases and squeeze for every single penny they can possibly extract. Fair or not.
Now more than ever, it's important for us to step back and reconsider whether we want to be billboards for these companies anymore.
For anyone unfamiliar, some good resources to have when starting your degoogling journey are below:
Privacy Guides - A list of privacy-respecting services you can use.
Plexus - A crowdsourced information bank of service compatibility with degoogled devices.

I used this guide: https://github.com/nextcloud/all-in-one/blob/main/reverse-proxy.md

I hired my VPS for around $200 a year (after comverting from Brazilian Reais to American Dollars). It gives me a VPS with 2 vcores, 2GB RAM and 40 GB SSD. There are many VPS providers that can offer you somthing with similar specs and and prices, like Hostinger, AWS and the likes. (Depending on where you live, you may actually find much better prices)
