The TP is a (love) cheat, who left his wife with a 6 month old baby to shack up with a more famous lady.
The TP pressured the race director for a mis-use of the rules in a title championship deciding race to ensure they won, which stopped a record-breaking championship win for globally a well liked driver.
Their "Motorsports Advisor" has had some very questionable opinions on race, and faced little to no censure from the team for public comments made.
The parent of their lead driver is a convicted violent criminal, and is hosted by the team like an old friend.
The team breached the budget cap in a winning year, and claimed the actions taken against them (which were relatively minor) as "Draconian", whilst steadfastly refusing to even come close to apologising.
Their lead driver assaulting another driver for an on-track incident in the garages after the race - TP claimed the other driver was "lucky to get away with a push"
Their treatment of "second drivers" in the team is seen as very ruthless, and even dishonest, for example in the case of Webber signing an extension under the agreement he would have equal terms, which was clearly not the case.
The Team have backed the often overly aggressive driving style of their lead driver regardless of the implications to the sport.
