Harris' takeover has been an an absolute success, but anyone claiming they knew it'd work out this way is lying or delusional. Just because we hit the low percentage chance that it all worked out doesn't mean people were wrong for thinking it was most likely a bad idea because all available history and information basically assured that it was.
That said, anyone that got vitriolic about it (on either side, tbf) can get bent. This is all uncharted waters right now. Being a dick about it either way isn't helping anything. Let's not pretend to know that anything is certain.
