I somewhat disagree here. The content on demand per patch simply isn't enough even if you do everything. 7.3 is only two weeks old and even if you're playing at a snail's pace you will have everything done unless you've deliberately put it off. The sole exception to this is if you play at an incredibly sparse pace, e.g., 1-2 hours a week max. While that definitely is the allotted time some players have, it's a comparable extreme to those putting in 30+ hours.
It should also be noted that it isn't necessarily the amount of content which is the problem, but rather the lack of longevity. Case in point, treasure maps and such are cool, but expecting that to carry you for 4-5 weeks is pushing it. Especially if Cosmic Exploration isn't to your flavour. Which, considering the drop off rate a mere week later was enormous. I'd hazard a guess in saying most people didn't vibe with it. So treasure maps are now carrying the load for over two months. Yes, there's the EX and Unreal, but for non raiders those aren't content. Even if you do dabble, the Unreal is two kills per week while the EX is 50 runs or however long your sanity lasts trying to farm beyond that for a sub 5% drop rate.
To be blunt, we've long since moved past the point of no return regarding third party stuff. The sheer number of downloads has far exceeding it being worth the risk for SE. Just to put this into perspective, one brought up recently on the discussion reddit has 5 million downloads. And that's only the third most popular one; fourth if you count parsers. What they're doing now is the only solution they will ever implement.They seem to cause more problems than they solve. Plus I heard of a cheat system that was implement within a monitor itself, technically independent from the computer, making it impossible to detect. People will always find a way around it and all it ends up doing is making it annoying to login or false positives. In any case, they see it as going against privacy laws in various countries.
