Any public network exposed infrastructure can be DoSed given enough resources. Bigger and more scalable infra can just sustain higher load, making a successful attack harder / more costly. That's why even medium-size commercial businesses hide behind something like Cloudflare.

So the way I think about it - the more efficient the underlying protocol, the more robust it is in face of a heavy load (legitimate or malicious), but ultimately if you're running a relay on puny VPS, it will fail relatively easily. The goal is to squeeze as much as possible from what's available.

Low barrier to entry doesn't not have to mean low robustness. Often does, but ideally something robust could be easy to build on.
