I don't know if I think it's likely he can make a success out of Parler. That's a very tall order. But I definitely think he's got a better shot at it than whoever has run it to date.

Completely agree. Put another way, it was far dumber for Parler's current founders and investors to try and create the Nth twitter clone in the current year than it is for Kanye to try and run it. Assuming he paid a reasonable price - buying Parler is probably faster, simpler, easier than creating your own app, which Kanye might not have the expertise/team to feel comfortable doing.
