You can say, like a lot of people will probably do, "well what a coincidence, he needs to get out of a contract and lo and behold, he was bullied"... but if he manages to produce those Whatsapp messages that's rather damning evidence.
Considering his comments after the chrono des nations, I think some of his Bora mechanics could likewise argue they were publicly bullied by the rider.
It cuts both ways. It seems a bit far fetched & a tad lacking in self awareness for a rider who trashed his team to suddenly pretend he was the young "bullied rider" who was too much of a perfectionist for Bora.
It's all about money & Uijtdebroeks wanting Visma, aka Visma who're either too poor to pay the fee or too clever for their own good (i.e. they saw a way of getting him for free/or for less than a million & seized it).
