I support their point of view and agree with their protest, but one reason against this could be the potential politicizing and weaponisation of Wikipedia. Do you want one of the largest collectives of human information to take sides (in any debate) and selectively remove its service?
I think I would prefer a banner or a landing page more as it doesn't introduce any barrier to the information they provide.
Because it is expected that they are as neutral as possible. People should advocate for encyclopedias, but they should not have opinions themselves. That impression can be argued to be wrong, of course.
