As soon as you have a form of editorial control ( which includes decisions about what to highlight and where to place it https://en.m.wikipedia.org/wiki/Editing https://en.m.wikipedia.org/wiki/Editing ) you seize being a platform and become something else. One could argue that maybe twitter could become a platform by removing any form of recommendation engine (including likes) and simply acting as an aggregator of reverse chronological feeds, but then what would the business case be? Social media has been eating up advertising by skirting in between the lines, acting as if they don't censor and are mere platforms (and thus aren't liable for falsehoods spread via them) while censoring and curating content heavily to ensure advertising cash keeps rolling in. I think it is time for (and with recent legislation proposals in the EU, am hopeful for) changes that either severely limit the type of advertising and control these wanna he platforms can accept and exert or simply makes them legally for spreading falsehoods and endangering the public via users they choose to jot exert their editorial control over.
