PowerPlay permits players to engage with all other players, regardless of game mode or platform, in indirect PvP with the option of direct PvP for those on the same platform, in Open, playing at the same time, with sufficiently good P2P connections to instance together.
Diminished for those who want to force all other participants to engage in PowerPlay the way they want them to? Indeed. However that's not a reason in and of itself to remove PowerPlay, as a game feature, from those players who choose not to play in Open.
Again, *if* PowerPlay had been intended by Frontier to require PvP then it would have been implemented in Open only. However, just like the BGS, CGs, Factions, etc., it was implemented for all players, in all game modes.
That some assume that PowerPlay is *only* for direct PvP is their assumption. Frontier seem to view it as a game feature that offers opportunities for consensual PvP (but don't force players to engage in direct PvP to participate in PowerPlay).
Changing the game from one that has no features that require the player to engage in direct PvP to a game that does is a fundamental change.
The most that Frontier has ever even mused about regarding PowerPlay and the modes was a brief period when Sandro mentioned that he was in favour of an Open play bonus to PowerPlay (to the Power only, not the player) - that was in March'16. When asked, in December'16, whether it was going to happen he said no and that there were no plans to do so.
Everyone is on a level playing field with respect to PowerPlay - there are no options available to only a subset of players. That some choose to engage in PowerPlay in Open only is, of course their choice - they cannot, however, force others to play the same way.
The storing merits in preparation for a snipe is certainly an issue - however it could doubtless be dealt with without restricting PowerPlay to a subset of players (i.e. those who prefer direct PvP and play in Open).
