Flat earther-ism used to be satire, too.
Now we have people killing themselves in attempts to “prove” that the Earth is flat.
Never doubt the ability of satire to fly over people’s heads at 10,000ft, and for those people to swallow that satire uncritically; hook, line, and sinker.
Sure sounds like labour to me.
And there is no requirement for labour to generate income immediately. A majority of labour is front-loaded, with income being back-loaded.
Server maintenance and updating code to work with current releases is still “labour”. Because sure as shit you’ve been doing these things… no hosting provider is going to let you go 10 years with zero updates or patches to the website or the underlying framework that allows the website to run. Because failing to do that is how entire hosting platforms get rooted and infected with malware.
