They don't "permit" this. I used to work on anti-bot technology at Google and we put a lot of effort into fighting botting, in particular on Gmail. We were quite successful at the time. Bot controlled accounts went from being a problem that was threatening the viability of the service to being fairly trivial. I don't know what it's like these days.
Anti-abuse teams tend to be relatively small. We aren't talking hundreds of engineers here, we're talking like maybe 10-15 engineers. When you look at the relative effectiveness of different networks, you can be comparing something as trivial and random as whether one or two people happened to figure out a good strategy or not. There is no need for conspiracy theories.
The costs of accounts on different networks is a reasonable proxy for effectiveness at bot fighting. My favourite site has always been this one:

From a quick check it seems Twitter is getting better at it. Prices used to be more like in the low $20/k range. Now the low end accounts are $45/k and if you want PVAd/profiled it's up near $90. Compare to Gmail where the price is more like $280/k. Or Facebook EN accounts, $120. Good to see my old colleagues doing such a good job!
In the case of Twitter, my view is that their relatively low performance on botting is a side effect of the whole social justice / campus politics movement. I heard from a friend who works there that their focus was switched almost entirely to fighting human abuse like people being nasty to each other, political extremism, terrorism, etc. If you remember, just a few years ago Twitter was being attacked in the media for being filled with trolling and nastyness. So of course that became their priority. Anti-botting took a back seat.
Nowadays there's suddenly a bout of anti-Russian hysteria. Suddenly bots are in focus again. There are conspiracy theories about botted accounts being used to convince people to change their political positions. Having worked in the industry for years I am deeply skeptical about this. I never once saw bots being used for political ends or anything even approaching it. There is a lot of disinformation out there about Russia right now from western sources, and a lot of paranoia that doesn't seem to be justifiable.
I'd guess RT does far, far more to create pro-Russian support than anything happening on Twitter does.
