> The reason you see Google, Microsoft, Amazon, and Apple get into "everything" is because they make so much more money than they need for their primary businesses. The reason? No, at least one major reason is they need to diversify their revenue streams. Google for example has been desperately trying to find something to offset their lopsided dependence on ad revenue for ages, because their party will come to a grinding halt real quick if they lose a large share of the eyeballs. Why do you think Google has given so much money to Apple to stay on their platform as the search provider? It's not a good position to be in.
