I literally setup almost everything I personally need in about a day on a VPS. As for services like LinkedIn I almost never got anything of value from it, it is worse than most job board it is filled with slimey recruiters these days and not a lot else.

I bought a NAS for backups with freenas and moving my email to a domain with a provider literally took me a few minutes (plugging DNS entries into my domain provider). It not that hard.

People should be making tools for helping people move away from platforms. I am personally going to write it all up and identify pain points.

I get plenty of business through (gasp) word of mouth and ex-colleagues. So I am fine.
