That's because the entire concept of the site has some fundamental flaws.

First of all the revenue jamboom originally calculated with turned out to be way off, meaning he's getting way less than he expected.
From shortlinks that turned out to be scam and never paid over shortlinks that pay only 5 times per IP and day or so, where the users use the very same shortlinks on several dozen different websites, where only the first of these sites a user visits per day gets paid, leading to complete termination of use of shortlinks on the site, up to an ever increasing amount of crypto related and ad financed websites hunting a shrinking amount of money advertisers are spending, the revenue of CMG wasn't even sufficient on day 1 and has gone downhill from there.

Next is jambooms reaction to the problem.
Any halfway logic thinking business man as well as any economist can tell you, you cannot cut your way out of a recession, the ONLY way to get into the profit zone is growth, but jambooms reaction is cutting payouts.
The less revenue he gets, the more he cuts payouts, subsequent more users run away, further reducing the revenue for the site, leading to further cuts in payouts, and so on and so forth, known as a "race to the bottom".

But jamboom is turning a blind eye to the fact that he's doing the opposite of what he would have to do to get into the profit zone, he's insisting that if severe cuts in payouts aren't enough then even bigger cuts must be the solution and since the revenue he's getting from advertisers by now isn't even enough to cover the extremely tiny amounts of money his users are still making, he's permanently coming up with further limitations to payouts, such as a limited amount of total withdrawals per month for all users combined.

Wanna bet? As a result of this "upgrade" more users will run away, the average time new users stay on the site will decrease and the revenue for the site will go further down.
It will take jamboom 2-3 months to discover that he can no longer pay $250 per week to the users and then he will come up with the next "invention" of how to further cut payouts that he will again try to sell as an "upgrade".
