While that is true, I do not believe that is why they are doing it that way. There's nothing stopping them from giving some minimal feedback that an update happened. It would actually be better that they did.

It is also suspicious how set they are so against users using an older version of their browser. Security is not a good enough justification. It is actually easier to use an older Operating System than an older version of Chrome.

This is clearly just to protect the integrity of their platform.
