Google Trips app to be discontinued on August 5

However, it looks like most of the functionality is being relocated to the Google Travel webpage (unless they pull an Inbox and only partially port things).
Seems like their whole purpose lately is to just create buzz on a launch, create a small dependent user base and then retire it when they realize they it doesn't contribute to their advertising base.
Honestly, I don't see the problem here.
I’m traveling Europe right now and I live out of Google Maps.
I've been slowly moving off of anything Google.
