Besides that you say that Elon Musk is a genius, that's normal because he is a businessman.
Do you mean all business men are geniuses?
And as far as I can see, he doesn't care about people, if it helps, he will get his money back.
If you have a blue tick that is some amount of fame, it is expected that fame comes with money, the $8 should not be an issue if you love twitter. Even if the fee was $2, you will still hear people complain about it simply because they are not used to it. We pay monthly subscription fees for other services already, so people can get used to it. If you love twitter, it is something to adjust to. I only just hope that they take extra precaution and make it difficult not to allow scammers easily get a blue tick with their $8.
