Social networks (Facebook and Twitter) are so negative about crypto projects because they themselves plan to launch their own cryptocurrencies. Therefore, they thus eliminate competitors.
This is not quite fair competition turns out. Facebook and Twitter are popular social networks above all. It seems to me to block people who are interested in cryptocurrencies is not quite correct and legal.
From the point of view of the law, they (Facebook and Twitter) formulate their position is quite interesting that many crypto projects are frauds, and the posts of participants in the bounty are spam ... While the fraudulent project is not proven by the court or other competent authority, but to call posts participants bounty spam is not correct because everyone has the right to freedom of communication. Maybe they like to communicate so peculiar? What kind of discrimination?
