Spending Bitcoins is good. You can compensate the company's dumping of their bitcoins, by buying back the same amount of bitcoins you spent yourself.
 
 
This line of thinking is a mistake. Please let me copy an answer I've mentioned in some other similar topics as well:

-------------------------------------------------------------

Even if you consider your bitcoins as long term investment, rather than spending money - what do you think will help raising the value of your precious bitcoins more:

• 1. Hodling your bitcoins and spending USD, thus only stimulating the USD economy
  
  or
  
  

• 2. Spending your bitcoins, thus stimulating the BTC economy, and immediately buying back new bitcoins (on exchange or circle or whatever), thus increasing demand for Bitcoin on the market.

Notice that the end result is the same: you essentially purchased some stuff, lost some USD, and kept your BTC. But with option nr. 2, you're actively helping to raise the Bitcoin price level on two ends: Bitcoin economy AND market demand. I really don't understand why even the most fanatic Bitcoin owners don't seem to get this

Especially if you're a Bitcoin fan, believer, enthusiast, investor, or hodler, SPEND THEM! (And immediately refill your stash of bitcoins by buying new ones with fiat)

By just sitting on your coins, instead of using them, Bitcoin won't grow! Spend them, and buy back at the same time.

If you are concerned about the 0.2% exchange fee that this will cost you: think how utterly significant this is when Bitcoin rises a few hundred % in value.
