Neither of those terms have a dictionary definition. I say it is old school.
Just because it lacks a dictionary definition doesn't mean you can call whatever you want old school and expect anyone to understand you.

There was the rather infamous comment by Gygax (I forget exactly where - The Strategic Review maybe?) where he said something to the effect of, "If you're not playing the rules as written you're not actually playing D&D." My impression has long been that it was seen quite readily as hyperbole, and in any case he wasn't trying to say, "play it MY way or you're doing it wrong," but that he was still trying to create an accepted core of rules to facilitate tournament play.
I've actually read the quote in question in the column it originally featured in, with context and everything. It's quite clear. And it's not singular, either. Gygax made plenty of other comments in plenty of other places that reinforced that mindset.
If your contention is that it was a single line that's being misinterpreted due to being taken out of context, I heartily disagree.
Now, whether or not players in general paid any attention to that sentiment or not is perhaps altogether a different issue. But it absolutely was the official line.

The idea of, "Do it THIS way or you're doing it WRONG," was a more recent phenomenon. Certainly in 1E Gygax made it quite clear that he accepted and expected that everyone would continue to make whatever changes they considered to be improvements on the rules.
No, it absolutely was not more recent.

I would have to see some citations to begin to accept the idea that "my way [btb] or the highway" originated with 1E.
:shrug: then you won't accept it. I don't care enough to convince you that I'm going to go research it. But that doesn't mean that you aren't wrong. The quotations are out there. Heck, you referred to one yourself.

And I wouldn't say that 3E EMPHASIZED that. It did, however, by omission of emphasis upon DM creation and control of rules governing their individual games, and by emphaisis of WotC as the sole source of "official" (and thus "correct") answers to rules questions, create in new players the impression that it WAS supposed to be, "Play by the rules or you're doing it wrong." That is the impression that it was VERY easy to take away from 3E whether they intended that to be the case or not.
If by that you mean to say that 1) the motto at 3e's release
wasn't actually "Tools, not rules", 2) The Player's Handbook
didn't say somewhere within the first couple of pages that the rules are suggestions only and that the GM is the final arbiter of how they work (paraphrasing of course; I haven't read that in years and don't remember exactly what it says), and 3) that it
didn't specifically give direction in the DMG that GM's should feel free to modify the rules as they pleased, even going so far as to give us some advice on things to look out for, and give us an example with the case of the Witch class, then yeah.
But since actually all of those things
were done, I'm going to go with you're just completely wrong there.
EDIT: I take it back. I got curious and did some quick Google searches. Dragon #16, July '78. Hooboy, that's a venomous condemnation of the very
concept of house-ruling or changing the rules (and this was before much of the AD&D was even in print yet!) And #26 from June '79, he's at it again--and
clearly referring to jumping from home game to home game, not tournament games (although he does mention them too.)
And even then, I know I've read others. Those two are not in isolation. And as for 3e being specifically designed to be modified and house-ruled, try this on for size:
