The span tag is, of course, a legitimate tag. Adding into already formatted html, so that font controls are both duplicated and in some cases contradicted is not a legimate use of it, however.
I don't dispute the WYSIWYG being bought in, but don't see how that information contradicts my impression that eBid's notice that they have updated it suggests a possible reason why formatting has started going wrong.
It has not being tidying up html, it has been corrupting it. Its new solutions might be better than its old ones, but using *both* is sub-prime.
