Praising the pick wasn’t so bad. The issues really arose when he was called out on it and chose to use Proton’s official accounts to affirm his view and went on to state:

• the republican party is now the party of the people and most likely to crack down on big tech
• The democrats have effectively betrayed their voters in favour of corporate donations
• This was Proton’s official stance

It was insane boot licking and incredibly poorly thought through. It’s fine for him to have an opinion but completely inappropriate to use their official accounts to spew such drivel and to state it was the official stance should have resulted in him being fired for damaging their reputation.
