I am planning to cancel at the next renewal because I just cannot see any value proposition to the business Platinum card at all. Maybe I'm missing something?

1. 35% airline rebate - becoming next to useless for first/business travel
2. Dell benefit - becoming useless
3. Adobe benefit - already useless
4. Uber benefit - useless outside the USA
5. inferior earning on airline tickets vs the personal Platinum
6. $10 wireless credit - ok ONE decent thing
7. loss of Sirius XM credit
8. $200 airline fee credit - only useful as long as I can still add to the United travel bank account
9. Hilton credit - $50 a quarter isn't much

So far I only see $320 in value - the wireless credit and airline fee credit - against a $700 annual fee, which may end up getting increased significantly.

I moved all of my business spending to the Blue Business Plus card which earns 2pts/$1 on everything.

Why would anyone keep the card? Especially if they have a personal Platinum for lounge access and 5pts/$1 on airline tickets regardless of channel?
