It's not an ad. This is the vivaldi community and this is a post from their blog
They did disclose they are using Lemmy for free adspace, that's why you should have paid attention to the arguments Misskey and FireFish devs have for implementing voluntary ads into platforms if people want. The alternative is letting corpos constantly worm their way in and use our resources and exert control over them for free.
I don't know why you think doing the Reddit fake anti-self promo thing will mitigate anything
I'm not sure if you're talking about a specific event but this community does not have any official connection with vivaldi. I am an independent user.
A Vivaldi blog post posted to the Vivaldi Lemmy community is an ad to you???
oh so vivaldi users read descriptive statements with caveman speak grammar. makes sense
