You know what is going to happen now? My best guess is, these companies are going to focus on smaller social media
platforms or Google's competition. { WeChat / Weibo / WhatsApp / QQ / Tumblr / Reddit ....} The opportunities are endless
with all the platforms that are out there. Bitcoin will not die, because large corporations like this wants to sabotage it.
Word of mouth is stronger than any social media platform.
i honestly agree with you, plan B is sure, the focus will now move from Google to it competitors. I used to know of one google competitor then called "mamma search" or so, don't know if it still exist anyway.
The move for Google banning ads is a welcome development from me, at least this will reduce the rate of scam project been advertised daily by google that turn to hurt people at the end.
It quite unfortunate that people have wrong interpretation to this ban
