The USA, where most of these profits flow to, appears to be fine with it. But it doesn't matter really. The cracks are appearing.
There was a review of gambling legislation in the UK which included considering whether loot Iboxes should be included (which would make them regulated like other kinds of gambling), but I'm not sure if it was finished before our government collapsed into stupid in-fighting and got changed a few times, it might have been forgotten.
Also this is why Microsoft created their policy on loot boxes (that anything in them will be earnable in-game) and why ZOS subsequently introduced endeavours - it's an effort to show the industry is self-regulating to discourage legislation. That and noticable shifts in public opinion. At one point microtransaction-driven 'live service' games were being held up as the future of the whole industry. Now games like Suicide Squad Kill The Justice League are being re-worked to take all that stuff out, and both Jedi Fallen Order and the upcoming Survivor used the absence of any kind of DLC or additional purchases as a selling point.
An MMO is different of course, because they're expected to get continuous updates and need to fund it somehow, but it wouldn't surprise me if they're also looking for different way to do that.
