"Let's also agree to disagree on the merits of using MediaWiki.org to teach people how to use MediaWiki. Yikes indeed."
Let me clarify: I have no issue with using MediaWiki.org to teach people how to use MediaWiki. In fact, that is how I learned how to use MediaWiki—of course I am not opposed to sharing information about teaching MediaWiki on MW.o. But the precedent for the past 10+ years has been to also share MediaWiki hosting/farming services. We have had a Hosting services page for many years now. The MediaWiki Stakeholders' Group is officially approved by the WMF to support all stakeholders, including both independent sysadmins as well as wiki hosts. This fundamentalist and exclusionist stance of only using MW.o for resources related to self-hosting MediaWiki is simply not shared by most members of the community. Nor is anyone here saying that MW.o should serve only to advertise a few services and MediaWiki-related knowledge should be gatekept and excluded—that'd be ridiculous and I'm sure everyone here opposes that.
As far as the purpose of the Used by template, I can understand that we should be inclusive, but surely we cannot include tens of thousands of wikis being displayed on this template? As far as I am aware, the template is meant to be for services that are general use, not for independent wikis. Sorry that this excludes your wiki, but it just doesn't make sense for individual wikis to be included on a template that displays each user of the extension.
I disagree with the characterization of spam. MyWikis, as well as our competitors, is providing a legitimate service related to MediaWiki and our service provides users a facilitated service to use this extension without them needing to install their own MediaWiki. If they don't want to use our service and want to install it themselves, that's fine with us. But for those who want to use a service, this template provides users an alternative. Every other person commenting on this discussion either directly or, for other related reasons, indirectly supports this template providing such a purpose. Furthermore, it sounds like your stance is heavily biased and even controlling what we're supposed to put on our own website. Everyone's links link to something reasonable. Nobody else here has a problem with how we present our links. We should have the right to decide what we put on our own website. We also strongly condemn any effort to violate our First Amendment rights.
Here at MyWikis, while we love Translate.Wiki in general, we don't want to use Translate.Wiki for our landing page. We already have our own translations in several major languages. Actually, we can't provide support in languages such as Japanese, so a translation to Japanese would be misleading because we actually do require the client to communicate with us in one of our service languages (sorry 😢).
I'll be happy to participate in legitimate discourse about reforming the template, but I'm not going to entertain any further comments made by the OP as there seems to be some ulterior motive that is driving their desire to delete this template, and I can't condone any proposals made in malice. If this discussion makes no further progress, I propose keeping the status quo right before this discussion was started.
