I think its an excellent idea, because some of their products are free so this is a way for them to get paid for their free products and the user doesn't have to have privacy intrusive profiled advertising thrust in their face when using a free product.

Crypto is also a hedge against local currencies as various country's, even the greatest nations can become unstable govt's very quickly.

Edit. It makes me wonder as the above has been downvoted, if this is why US cpu/gpu manufacturers are now disabling things that make mining crypto harder like Intel's AVX-512 and nVidia's changes to prevent GPU crypto mining, whilst using global warming as a straw puppet.
