Well, I was there at the time and this is what I remember. The Gmail spam filter is very email specific, it's not like you could just point it at a stream of chat messages and get good results.
Independent XMPP operators don't have anywhere near the spam problems Google has/had. They're just far less appealing targets.
I'm not saying they didn't have spam problems, but that's the kind of thing they certainly had resources to solve. They already had such systems due to Gmail, and even independent XMPP operators have a pretty good handle on XMPP spam these days without even a fraction of the resources available to Google. It was more a matter of priorities du jour for the company.
