Trump has repeatedly threatened media companies he thinks have wronged him with specific actions he's said he will take as president. Bezos has a whole business empire to worry about that goes way beyond WaPo. He doesn't need a petty president trying to wreck his bottom line for 4 years. And with a business that big, Trump has a lot of ways he could cause trouble.
Regardless of the motive, I do not view favorably his interference in the newspaper. If anything, he should have left editorial decisions to the staff.
We have a potential future president who, putting it very charitably, espouses the ideology of "For my friends — everything, for my enemies — the law", and in the least surprising development ever, billionaires suddenly warm up to this guy. Many such cases.
Yes we have a reason. Trump threatens media companies and individuals he believes have wronged him - loudly and often. If someone came to you and said they aren't going to a party, and you knew someone at that party had specifically threatened to beat them if they attend the party, do you have "no reason" to believe that the threat of a beating is a likely cause of the action (or in these cases, inaction). Especially if that person has a long history of attending that specific party?
