I think that was much more the case when the brand was the only brand. When the company lived or died by its chocolate, or single brand of appliances etc, even if the founder was gone, I think a lot of care was taken. Now a brand is commonly one of 10 or 30 in a portfolio, I don't think there's much care left.
When the parent has a dozen appliance brands you can play loose with the trust of any or all. Half the product may be little more than badge engineering. When there's dozens of food brands in the book, or the market leading brand gets bought, it's virtually certain they will be worse than they used to be. Often quite a lot. The perception of the brand might carry that for years.
BF is an odd one as it's trying to become a respectable news outlet, without letting go of the junk that made them. Now the perception has to go the other way, up. A much more difficult move.
At least (for now) if you buy a Samsung or LG you know who to be pissed off at.
Sometimes you only need to buy the reformulated market leader once to realise there's no reason to ever buy it again.
Trust may turn out to have been a 20th century concept.
(like Buzzfeed's equally dodgy counterpart, News Corp and its different newspaper/news site names).
At the time, my view was that, Buzzfeed, and others, were just attempting to ride the tsunami of free Facebook traffic for a wildly bloated valuation in hopes to hoodwink a legacy media company into buying them before the party ended. They spent what would have been their profits, and then some, on shining their turds. It was a gamble and they mostly lost.
