Enshittification is coming:
Beginning in the next month, when users click Bitly links or QR Codes, they may see a preview page prior to being directed to the destination URL. The page includes information about the link destination and may include advertising.
Well, they give the option to remove the ads altogether for just $120/year 😉
Although literally nobody would pay that ransom (100000x the actual server expense) to remove ads from their own links
