The move from these teo trusted sites is to protect those that are new to cryptoworld that are vulnerable to online scams using crypto to get money from innocent people. This is actually good for everyone. Not all people see the goodness in this act by facebook and google. If this gets implemented, people will only buy bitcoin in legit sellers and websites which means many people will now trust that they will not be scammed. The only reason why some people didnt invest earlier was because of fear of being scammed. If google and facebook will remove this vulnerablility then this will enhance the value of cryptocurrency and might bring the price back up.
The ban from Facebook and Google has a positive impact, with this ban we hope to handle fraudulent projects so that Bitcoin users will be spared the risk of fraud, as we all know that lately a lot of ICO is a fraud. With this ban I think the scam project is not easy to cheat and also reduces cheating.
