>The thing is, theses users don't come to my product page for getting updates for example, so I think it's a loss for me because I can't reach them and talk to them.
You assume that they would buy in in the first place. I would not spend a penny on 95% stuff I pirated. Most of the stuff was a one time thing, like game was too boring (I would request a refund), game had too high requrements, so I couldn't even start an episode, music was not interesting after literally one song from whole discography etc.

Things have FAQ? I've never seen them.

>I have faith that some of my pirate users can become my clients one day
I've pirated more than 1k of PC games, my steam account has 97 tites right now, and there is also GOG.
Try to make your stuff easy to reach, steam, gog, https://itch.io/app, try to build hype around your game, it's easy now no reddit in /r/gaming show some cool/funny scene from the game, make announcement on /r/linux_gaming that game is available from first day, etc.
