I was thinking about the recent story about the DB looking for windows 3.1 administrator.
A classic issue I’ve soon working in heavy industry is that hardware last longer than windows version. So 10 years ago, you bought a component for the product you design or a full machine for your factory which only comes with a windows XP driver.
10 year latter, Windows XP is obsolete, upgrading to a more recent windows might be an option but would cost a shit load of money.
I have therefore the impression that Linux would offer more control to the professional user in term of product lifecycle and patch deployment. However, there is always that stupid HW which doesn’t have a Linux driver.
There’s plenty of support for Linux. REHL, for example; their entire business is selling support. Suse, CentOS, and Debian all have people specifically to support enterprise.
Sure, there’s not a hotline with a guy on the other end who may or may not be more knowledgeable than a 5yo post on Reddit or stack exchange or wherever… but they do have enterprise-grade support
