What happened is that they became progressively less common in informal/spoken American English, and then only very recently in a fairly sudden transition most commercial writing abruptly lost the attention to grammar, spelling, word choice, etc., that had been previously the norm for formal writing because who has time for that?

And the internet has made English American, newer generation in EU are now writing more American English than ever.

It's common to avoid adverbs in general when writing fiction IIRC.

Not by removing the ly though, but by choosing a more expressive verb.
