@T0m, I'll be honest now and say that while as much as I would want the scene to actually grow more (any amount will be helpful but also really hard due to the age of the game), I also would hate myself for seeing any action that is done by ETF2L to hurt the top of the scene just as well.
It's a completely double-edged sword in my case, I personally want the top of the scene to stay healthy but at the same time I was very keen when the global whitelist was initially released to hope that it would gain more people around. Surely that's not true as it has been pointed out already in this thread, but the point of it was not to hurt all the experienced players that have already been playing this game for several years already only to find out that a Heavy can heal himself with a banana now of all things.
Then again, if money is the only thing that people are looking up for, all I can say is that money was never even a big thing in European TF2 in these past 4 years that I am personally aware of, aside from Insomnia LAN of course that just barely is also hitting similar numbers to what there are currently in NA. But if winning around 80€ per player for something that a whole team puts 3 months of effort into keeps the top of the scene alive, then I guess we have no other choice then.
