Click baity headline. Here's the actual quote:
“There were Romulans—there was a whole thing. The idea was that Guinan’s bar was presented as a normal bar in Los Angeles, but if you knew the right thing to do, you could go into the back through the telephone phone booth and that was Rick’s Café and it was a stopping point for all these different species that were actually there on Earth with a ‘Do not interfere’ thing happening. So you had a lot more Star Trek happening in the backdrop of it. Ultimately, the powers that be at that time were like, ‘This is too much.’ But there were some really good ideas there that were pretty cool.”
Sounds like they wanted to throw in a bunch of random alien species cameos that would have done nothing but distract from the plot. Frankly, there's too much of that in Season 2 already. We don't need young Guinan, Gary Seven's team, a Soong, visitors from Vulcan, the Borg Queen, and Q all mucking about with Earth. Pick two to three of those and actually develop them.
