Not having soap (or toilets or running water for that matter) never
drove away eatery patrons before those became common. Do you think
they became common because someone made a business proposal? Did the
patrons protest in outrage at a lack of Dove Coconut Cream? It
happened because someone up top decided that's what is supposed to
happen. This is the only way lossless audio will happen, as well.
10 million GB per day seems like a lot until you realize it's a
fraction of a percent of what they use total. In 2012 they paid
roughly 1 cent per GB uploaded. Prices have improved dramatically, so
those ten million GB are going to be only tens of thousands of
dollars, if not less. There are streamers on YouTube who earn more per
day. That extra upload bill is going to be 300-600k USD per year.
That's literally nothing at their scale. Google earned 134.81 Billion
$ from advertising in 2019. Even $10m is less than one percent of one
percent. For a comparison, a senior google engineer's salary could
cover that yearly bill and top it off. Maybe two on a rainy day. The
consideration that this could hurt their bottom line in any way simply
does not exist.
