The only way money glitching affects you is if you actually believe that glitches are delaying Rockstar's output of content, which is just silly, and you only have yourself to blame. Like Raavi said 6 pages ago, there are multiple different teams that work on different things.
While there likely are different teams that work on different things, do you honestly think that R* is gonna release new content if there is a known glitch available to "buy everything for free" at the time that they planned to release it? That would just be stupid.
Let's say High Life was supposed to be released this past Friday. Then, the "Buy everything for free glitch" came out. Do you think R* would:
A: Release High Life anyway, knowing full well that people would glitch anything and everything in it in 5-10 minutes and be right back to bitching about there being "nothing to do"
B: Since there hadn't been an announcement about the release, simply delay it, fix the issue and have a harmless Snapmatic contest (that, to players, came out of nowhere) to pacify players until they were sure that all of the stuff can't be glitched in 5-10 minutes.
Which do you think they'd choose?
Just because R* doesn't come right out and say "Glitchers and Modders are delaying content releases" doesn't mean it isn't happening behind the scenes.
Even if R* did come out and say it, it's not like you'd all stop anyway... Hell, some people are demented enough that they'd do it for the sole purpose of delaying new content.
That's because most missions are a complete waste of time. The payout nerfs ensure grinding missions.
The only reason anyone would need to grind missions would be because they choose to.
I played for around 4 hours yesterday. Didn't play Rooftop Rumble once. Did what I wanted and still made a pretty penny... All without glitching or farming.
People were glitching well before the payout amounts changed, so that "payout nerfs ensure grinding" is junk, as is the argument that "people glitch because the payouts are too low."
Again, if this is your attitude, why should R* release any more content?
When heists come out, I can tell you exactly what's gonna happen with people who glitch or are only concerned about money... They'll find the highest paying heist, play it and then:
The people worried only about making money will start farming that heist over and over... The highest paying heist (assuming it pays more than Rooftop) will be the "New Rooftop Rumble."
The glitchers will bitch about the payout being "too low" and use that as yet another excuse to not play the game and instead, simply glitch money.
