No, it should not, because as long as we have net neutrality anyone can start a new "platform" is no other "platform" will let them speak. The problem is that ISPs are gatekeepers and typically enjoy local monopolies; there is no such problem with edge services.
what about payment services like patreon, paypal etc? (my personal theory is that google etc love the stronghold they keep in online media and do not want ISPs to mess with it, hence why they are so supportive of NN regulation)
As for Google et al., I do not understand the connection. A neutral Internet is one in which a small startup competitor faces one less barrier to entry, so how does NN help Google maintain this so-called "stronghold" in online media? Net neutrality is the reason Google does not have "partnerships" with ISPs to be the sole provider of web search to the ISP's customers, or Facebook being the only social network you can access, etc.
shouldnt that extend to the medium level? be it netflix , youtube etc. i.e. platforms should not be allowed to deplatform?
