On the very page you link to:

People use the term clanker both online and in person to comment either seriously or lightheartedly on the rise of AI. Some oppose using the term, however, because they say it perpetuates other slurs throughout history.

There is also this text shown as an example:

...with the upsurge of AI and AI-related technology (robots, for example), people have been going around calling said technology "clanker" as a slur… I know it's probably [just] a joke [...] but I can't help but feel like it's incredibly tasteless. @Informal_Radish_1891, r/blackladies subreddit, August 1, 2025

Now that's interesting isn't it ? Wonder what Informal_Radish finds so tasteless about it ? Here, I found the post in question. Unsurprisingly, she and some of those who replied echo the same concerns I mentioned.
