It's not fake FUD. It is an issue I have raised before. We should be conscious of it rather than dismissing it.
Well, we could decide to rename that thing - maybe just XEL? Or we could write it with a "k" at the end? We could also try to find out if this would be necessary first. It's up to you @community.
I do not think it is necessary, at least now. If/when elastic team meet problems due to trademark then community and team could consider rebranding. IMO
