Pretty sure they are implying that the actions of the current president/administration are causing people to re-evaluate US dependencies. I don't really understand the first half
That is indeed what the comment seems to be implying.
"No meaningful European competition" might be a bit too strong. There are many great EU hosters. OVH, Netcup, Scaleway, Strato, Ionos, Exoscale, to name a few. But Hetzner is probably the biggest and has the best name recognition. Doesn't hurt that their prices are among the best in the industry
(I also prefer comments that are clear without insinuations).
