The twitter comment was specifically talking about television networks, so your comment about you not watching tv is an automatic submission.
That page you linked as your evidence is featured on neither the front page of
https://cnn.com or
https://www.cnn.com/politics. Having a page for it hardly shows that it is being treated in the same manner as the Trump Impeachment. You can go there yourself and see that it is wrong that it is being treated in the same way.
If you go to
https://cnn.com and search for "impeachment" you see some non-featured links to "Fact check: Republicans make false, misleading claims at first Biden impeachment inquiry hearing" and "Republican witnesses directly undercut GOP narrative at impeachment hearing"
On television the Trump impeachment was treated with as much importance as a major terrorist attack, that everybody just had to know about, which it is clearly not in the case of the Biden impeachment.
