You cannot be serious if you believe they should be pissed about PSG wanting to sign Wijnaldum and offering better terms. This is literally how the free agent market works. Multiple team usually make contact. A few might offer concrete terms or a contract offer.
Wijnaldum has been on the free agent market since at least 6 month ago, when it was certain he is not renewing with Liverpool.
PSG had all the time in the world to prepare their super-offer and contact him.
Why didn't they do it all that time, but they do it now that it is leaked all over the press that the player has reached a personal agreement with Barca and the medical will be scheduled next week?
Nothing to do with free agent market.
Everything to do with pety chairmans and clubs who want to take again revenge in their primitive way of understanding things
What political power? We are the outcast in European football right now because of the ESL fiasco, while Nasser Al-Khelaifi is the chairman of the ECA now. If we had any power it has dwindled a lot.
Anybody can hijack our deals or outbid us last minute as long as the other party (the player and the agent etc.) didn't break or breach a legally binding contract. As you pointed out, we hijacked Malcolm from Roma and some might say we did the same to Bayern by getting Dest (It was said that Bayern was leading the chase and reached a personal agreement with Dest, however we came in late and submitted an offer to Ajax and got Dest because both Ajax and Dest preferred us, something like that). As long as there was no official, legal-binding contract signed, anybody is free to come in last minute to outbid another club and change the player's mind.
Nothing Laporta can do.
The whole middle paragraph is the perfect description of why some stage of the negotiation should become legally prohibited for other clubs to enter in.
As for the political power, sure he has power as ECA chairman.
But there are many cards Laporta can play. At least there are people of power in football that detest the 'new oil money' attack of Qatar and Dubai.
There are coalitions he can make and actions he can take now or in the future, not directly related to transfers, to get the message across
At this level, Laporta is a shrewd politician.
