Well, Wakeman initially said he wouldn't attend but then changed his mind in January:
“
I am very pleased to announce that as the Hall of Fame have now agreed to present Chris Squire’s wife with a posthumous award acknowledging his massive contribution to YES, I have agreed to attend the Induction ceremony in New York to both stand proudly with my fellow band mates Jon and Trevor and also to watch Chris’s wife Scottie collect this well deserved award on his behalf."

So back in January it seemed like it was a big deal that she get some acknowledgement. Squire's wife Scottie wrote after the Hall of Fame event:
"for the record....I was supposed to talk after Rick. He said he was going to introduce me. I had a very nice speech prepared to honor Chris, and Xilan and I wanted on Chris' behalf to thank everyone, especially the fans (but mainly Xi and I wanted to honor Chris for the great musician he was.) I am not here to blame anyone for why we didn't get to speak, but there are time constraints with these shows and the whole time Rick was talking there was a monitor flashing "wrap it up". Also, for the record, I didn't refuse to go up and talk. After Rick was done he handed me the award but everyone was just being ushered off stage. The whole thing was awkward. I know Rick's heart and he didn't do anything to diss me, Xilan or Chris. I think it was just not planned very well. I really should have gone and spoken before Rick..."

It seems like she's okay with it, which is pretty classy of her. I really don't think Wakeman wanted to take her time. He's a funny guy, and when he gets going, he just keeps going. It just bothered me that he couldn't help himself.
In the end, I just see it as another example of how dysfunctional Yes has become. Amazing musicians, but they're human, too.
