Unfortunately, this is a common tactic. Walking back a previous wrong assertion allows one to frame it as a virtue--"we corrected ourselves!"--in order to avoid talking about the original vice of being a copy-and-paste propaganda organ for the state.
There seems to be a very tight integration between the government and the major media, and this is a real problem. It's not surprising, as a journalist that is a burr in the saddle of government power soon finds it difficult to talk to government entities. But it is a problem if there really is no journalistic independence. In recent years, journalists seem to be little more than Twitter researchers. Complete randos from the Internet, some of whom were clearly a little bit mad, got closer to the actual truth than the "trusted experts."

Readers aren't parsing sentences this closely and comparing to previous statements.
Unless they come out with an editorial statement apologizing then they aren't really serious about their own involvement in censorship on behalf of those in power.
Damage done.

From April 2: "The prime suspect is ‘natural’ transmission from bats to humans, perhaps through unsanitary markets. But scientists don’t rule out that an accident at a research laboratory in Wuhan might have spread a deadly bat virus that had been collected for scientific study.”"
Couple that with the admission from Cotton: "Now, we don’t have evidence that this disease originated [from the lab]"
Numerous experts in the field backed up the idea that the virus was engineered or came from a lab.
Even Cotton followed up with further clarification of his original tweets.
"I am pleased to hear you now distinguish between possibility virus was engineered bioweapon (which can be dismissed) and possibility virus entered human population through lab accident (which cannot--and should not--be dismissed)" - From Feb 16, 2020 (referenced in Feb 17, 2020 in Washington Post.

Is it bad that people update their thinking when new evidence presents itself? No.
But that doesn't mean people who pushed an idea without evidence should be lauded. A broken clock is right twice a day, after all.
"The Post originally described Cotton’s remarks as “debunked” and a “conspiracy theory” in a February 2020 article. But last week, The Post rewrote the article’s headline, softening “conspiracy theory” to “fringe theory” and noting that scientists have “disputed” it rather than “debunked” it."
