I wonder why people complain the most for things that are literally FREE. Every day people talk about faucets online and rain in the casinos I play in and I wonder, they get these things for free but they spend so much time asking for more.
I think it has a connection with the real life casinos giving away free stuff. I know they don't do it for the small timers (and even some places give away free drinks to any gambler who sits on any table) so people expect the online places to be like that as well. Don't forget that casinos are built to take your money away, so whatever you do to make that money back is fair game in peoples eyes and if one casino offers more free stuff than the other then they will go there.
So, every single online casino in the world is racing with each other on free stuff, deposit bonuses, promotions and many other stuff like rakebacks and all that. Whoever gives the most free stuff will get the customer but you also have to be trustworthy as well. Fortunejack is trustworthy because it has been around since the year 1814

so all there is left is complain about the free stuff.
