More cruel when the team is Red Bull. They do this mid season change quite a bit more often than the rest of the field combined.
And thus it's no surprise the Red Bull junior program absolutely sucks these days. Because no one wants to sign with them.
They were good when they were the only junior program in existence (pretty much started up when Renault and Mercedes dropped their original junior driver programs -- remember when Michael Schumacher was a Mercedes junior driver?). But when everyone saw how successful the Red Bull junior driver program was (and it was -- Vettel, Buemi, Klien,
Alguersuari, Liuzzi, Ricciardo, Vergne, Kvyat, Sainz, and at the tail end of their success, Gasly and Albon), they all started one. Heck, even Williams developed one (which Logan Sargeant was in).
Now, no kid wants to sign with Red Bull. Just look through the F2 and F3 ranks -- if you ranked them all, the Red Bull junior drivers are essentially all on the bottom. Even Max Verstappen wasn't really a Red Bull junior driver. He signed with them as a "regular" driver, as he wasn't hooked up with any junior driver program. He was also eyeballing Mercedes. Red Bull won the Max lottery because they promised him an F1 ride immediately. It had nothing to do with bringing him in as a junior driver and grooming him in the junior series.
Their "greatest" product nowadays is Yuki Tsunoda, who's only still in that seat because of Honda (and the fact they have nobody else to replace him). Liam Lawson is the only current possibility of moving into F1, but some are still lukewarm on him. And note they didn't pick him to replace de Vries. Dennis Hauger is the only other Red Bull junior driver who is accumulating a decent resume. The rest of them are miles away from being F1 material.
