It really depends on the business.

I worked for two smaller businesses (team of ≤ 10 software developers). One was mismanaged, ran by very unpleasant people, and abusive towards employees, resulting in a huge turnover and a “dead sea effect”. The other company got government grants because the owner’s relative was a politician, and had ridiculous surveillance software on developers’ machines.

Ironically, the most “human” and enjoyable work I did was working on internal legacy software and code rewrites for a huge corporation before and during their move towards agile and modern “conveyorized” approach to software.

When I ran prosody a few years ago, I did so without docker.

I did try snikket in docker though, and it looks like it is still actively maintained.

A lot of them are getting blocked too, presumably by datacenter IPs. I suppose it’s possible to run it off a residential IP.
