It's not that breakfast is "no longer included for platinums at Courtyards," as if this is some sort of recent change.
Marriott has 19 brands. Most Marriott brands do not provide breakfast as a brand standard.
Only four Marriott brands offer breakfast for Gold and Platinum Elite Marriott Rewards members, and, even then, only if the property is not classified as a Resort:
- JW Marriott
- Autograph Collection
- Renaissance
- Marriott Hotels
Technically, the Elite member breakfast is limited to continental breakfast and is limited to the Elite member and one guest. In reality, most hotels of the four brands go above that minimum standard (including the full, hot breakfast buffet in the restaurant if there's no lounge or the lounge is closed) -- but they're not required to.
For details about the Elite member breakfast benefit, see

There are some Marriott brands that provide breakfast to all guests, but this has nothing to do with the Elite member breakfast benefit:
- Springhill Suites
- Fairfield Inn
- Residence Inn
- Towneplace Suites
Courtyard is not on either list above.
There are properties that provide breakfast, either to Elite members or to everyone, even though not required to by brand standards. Also, there are rates that include breakfast.
