Well, my point being, we have an incredible degree of trust that these companies will operate in a continuous way, that their values will be unchanging. I too work at a large ecommerce tech company, and I can't see it suddenly changing. if you look at Yahoo, who knows in 10 years wether Verizon doesn't sell it off and the eventual owners decide that an ad-enabled 'look at everyone's emails' site wouldn't be worth the cost of buying Yahoo Mail's data.
