If in fact this formula has been set for the following weeks then I am sure the gaming activity of users will decrease drastically, they may even go looking for alternative casinos. To be sure we have to wait for the next weekly bonus.
I'm not expecting to see any correction of the bonus amount on the next week. And I have already started to search for casinos with better bonuses than Stake. I'm not going to leave Stake completely though. Occasionally, I will try to find my luck on Stake. Their marketing team has made a lot of adjustments to the bonus system within the last few months.
Who knows, maybe they will try things differently for the bonus amounts in the future, at least, because the backlash would be hard enough to make them notice it, with one eye opened at least
