Yep, totally agree. I'd like to add though that parsers are still an acceptable practice privately (just not officially allowable). So I mean, going out to get the parser isn't exactly earth shattering for PC players, if their goal is to improve right now.
I mean, speaking from experience, I didn't bother with parsers in this game until several months ago. I knew my rotation and my numbers were pretty close to expected (got an extra ~40 DPS maybe after adjusting from parsing, so not exactly a big deal outside of Coil). Knowing your rotation/priorities, which is just guide related rather than crunching numbers, is usually enough to get the majority of your output going. Parsers typically serve to squeeze out that extra bit to perform as best as possible, instead of just "good". In the case of console players, seeking out a friend or something to help parse you isn't really difficult to do... it's no different than asking for help for any other thing you might do in this game. That's the way I see it, and I honestly think the way the devs/Yoshi-P see it. They seem to like to believe the player base doesn't need everything handed to them when the acceptable resources available aren't that much of a problem to pursue... I have my own pessimistic doubts on that glass half full perspective, but that's me lol.
Something to keep in mind is that, this person is likely new. If this were during the earlier days of ARR, their i120 would be... some i70 and a bunch of i55 probably. It's easier to get mad at new or ignorant DPS now, because we know what the potential is for said gear. The problem is that it's the exact same situation as that older one where the DPS would still be in i55+ gear, but people overlook that concern. Then again, there are also a lot of people that are just being lazy (this is probably the most common one we encounter). Unless you paid for clears, you're probably quite aware of how to play if you're in some Dreadwyrm or T9 stuff.
