I’m just pointing out the perceived contradictions in the ‘requirements’, and explaining why you were likely getting “the Linux recommendation” you complained about in your edit.
Also, this isn’t an ‘RFP’ - you aren’t offering to pay anyone anything to do your dirty work. You asked for advice and appear to get mad when some of the advice you receive is not to your liking. Don’t act entitled, it’s literally free help/advice in a public forum. Even if someone’s suggestions don’t help you, they might help the next person with a similar situation/concern that comes looking for advice.
