Unlikely, could also just mean congested upstream routes/bad routing somewhere. Your VPN means traffic takes a different route that isn't affected.
I'm 99% sure VM don't do any throttling (on downstream at least).

So while they were not throttling, they somehow messed something up elsewhere and for months my VPN was significantly faster than an un-VPN'ed connection for some bizarre reason.
