Maybe the players (and manager) are sick of the board cutting corners of signings and it's a underhand threat to the board.
The players he would have upset are the ones we need to improve on anyway.
Or maybe he just said it because he wanted to!
But it isn't his job to do that, that is Pochettino's job if he is unhappy with the board. As a player, you have signed your contract which presumably you were happy with and if you now feel you should have input into signings and budgets then you need to retire and become a manager. Until then, do what you are paid to do.
Just because those players aren't up to his perceived standards they still play a role within the squad. You can't have 25 players all of the level you would expect for a starting 11, its about the squad.
As I've said, he may well be right in the content that he discussed but he is the wrong person discussing it. Not one person on this thread can persuade me otherwise.
