So, let us be very clear. The article says it "could show immune evasion..." and that sounds scary. But in the next words it says, "it is too soon to tell". (emphasis mine)
That "could" does a huge amount of heavy lifting. It is not, "We have preliminary evidence that suggests this to be true". It is merely, "this is theoretically possible." It is a line intended to raise anxiety, likely worded that way to get you to keep coming back to the news source to learn more - in other words, clickbait.
Do note the "if" in my post.
The issue is that there's apparently a large number of mutations on the spike protein head, which is where you expect problems to come in. Doesn't mean they will--they've been looking at cases for less than a week now if I understand it--but with the numbers of such, this is the kind of variant you'd expect to be a problem, if you're going to get one, with immune responses.
Which could well end up meaning nothing, but its also absolutely the case where you don't want to wait around long enough to be sure to take precautions.
(To be clear, this is not me disagreeing with your point on your prior post that you have to have some line you reach before you start early reactions, but this does not, on the face of it, seem a routine variant).
