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.
Yes that would be one way to get round it. In fact I may be wrong but I think Elastic itself may be considered too generic to be copyrighted anyway. So Elastik (assuming nobody else has used it) would be better.
