I take the "Author is Dead" approach here. Whatever was intended these mechanics lead to some really excellent organic experiences. Whether that's PvP in the strictest sense of the word or not I don't care. It's just too cool.
Well I take the "Author is trying to damage control and just makes things a lot worse" approach myself. We'll see what's brewed for pvp, or putting an end to it, in 2020 I guess.
I'd agree on BGS. It was hand on heart co-opted by all the E-napoleons, seen as that was all we had at the time in terms of metric based dominance. Worse, FDev fuelled that by grading their interactiobs with PF based on how good they were at dominating the BGS.
But I think you're wrong with PP. It seems to be designed (at its heart) specifically for that kind of gameplay.
PP failed hard to condense players around contested systems, because there is far too many of them. Three powers were largely enough, instead of the many pirate/scientologist/space elf flavors we got.
