It's not really false advertising (although I can see how can seem that way in these cases), but a general problem with Choice hotel websites being out of date.
Another hotel, the Comfort Suites near SNA airport in Orange County CA brought back its full breakfast buffet over half a year ago at least, but it still says "grab and go breakfast" on its website. So in that case it offers more than the website says, not less. But it was offering "grab and go breakfast" earlier during the Covid era.
So different hotels are out-of-date in their breakfast descriptions in both directions.
