I wouldn't call it groping... embracing is more like it. Embracing naked. Still ... nice work if you can get it.
No, there's not much Joss can do about it. He doesn't own the rights to Buffy or the other characters in the Buffyverse. Sounds like the situation a couple of guys named Siegel and Shuster got into about 70 years ago, huh?
If Joss had created Buffy in a novel, he would hold the copyright. But it usually doesn't work that way when you create something for a TV network, a movie studio or a comic book company. You're a hired hand, and the company owns the rights.
What about the new comic? This "reBuff" uses the familiar characters, but retools them for the present, like Ultimate Marvel, post-Crisis/etc DC, or Smallville. I haven't read it yet, but the first issue from late January is in second print already, and I I think I might check out this series.
