Hey man, I’m sure you are not offending anyone. You have your own preferences and so do others. It’s obvious you can’t live without the auto-liners in a flight sim, while, for example, DCS World and IL-2 Sturmovik users wouldn’t care about flying them in their sim of choice. It’s normal to have a preference. As for your opinions, some are very valid and I wholeheartedly agree with them, while some are not. And that’s my opinion too.
It’s your life, money and time so you decide how you want to enjoy them. Hope you find peace in whatever you do 
FWIW, many people still use XP10, FS2004 and FSX. They develop addons for it too.
