YouTube has been running on a loss since they last posted their info some handful of years ago. I think Susan was being pressured by creators to be transparent or something. YouTube has expanded well beyond what it used to be and hasn't demanded money to compensate. It just keeps getting bigger and bigger and Google/Alphabet has been fine with that but clearly aren't anymore.
Alphabet makes money in other areas, yes, but YouTube specifically is the problem child that keeps begging for an allowance. So, how does YouTube fix it? How do they save money? By kicking off the freeloaders. You watch ads, contribute your 13 cents for the day, then fuck off - or you can buy premium.
Like I've said before, if you hate the big companies fix the tax laws, don't bitch about them charging you for the service you've been getting free of charge.
