Everyone is applauding this because they hate Trump, but take a step back and see the bigger picture. This could backfire in serious ways, and it plays to Trump's base's narrative that the mainstream media and tech giants are colluding to silence conservatives (and maybe there could even be some truth to that.) I know the Valley is an echo chamber, so obviously no one is going to ever realize this.
Completely agree with your second point though (not that there is any collusion to silence conservatives - but that this whole situation will be taken that way and used to energize that base).
What is the most annoying about this, though, is the tweet they chose to "Fact Check". (I use quotation marks because "fact checking" by linking to CNN and WaPo is not fact-checking at all, rather an appeal to a different authority.)
The tweet they chose to police is speculation about the future. If I say the boiling point of water is 50 degrees, you can fact-check that. Its an objective truth that water boils at 100c.
If I say mail-in votes will cause election fraud, you cannot prove or disprove that statement. All you can do is show me someone else's statements, opinions, and predictions on the matter.
Given that Trump says so much objectively false stuff, it annoys me they didn't go after one of those tweets instead.
You catch the most flak when you're over the target...
I'm not sure I believe that claim. I think that looking at past history of voting fraud shows pretty conclusively that _vote by mail_ fraud has always been a very low percentage.
Sure, it's possible that _some_ fraud might happen, but looking at data from Oregon, it's happened two times in twenty years (_from my reading of the conservative database that was linked somewhere yesterday -- sorry :) -- I might be off by an order of magnitude, but it's still small_). That seems like an _extremely_ low incidence rate, and seems a small price to may for the idea that maybe more people will be likely to vote, due to not having to stand in line at polling places, deal with vote suppression efforts, or even just because it's more convenient to fill it out on your own schedule ahead of time.
Now, many will say that states like CA and other large states, who haven't had a large-scale rollout of vote-by-mail with the history and planning that Oregon had, will face more fraud than Oregon did. I think that's actually a very believable point -- we are not going to have a perfect rollout. However, I'd also like to point out that we've had two decades of electronic voting machines that have been proven to be absolutely insecure, as well as numerous cases in other states of voters who have been unable to vote because their polling places were under-staffed or closed too early.
Voting by mail is a proven method that scales well to ensure that larger portions of the populace have the opportunity to vote. It's being considered in light of wanting to limit in-person gatherings. It very unlikely that it's some conspiracy to promote fraud.
