Blowing it in big name Hollywood actors when all you need is a decent voice actor for 5% of the price.
Nobody is going out to see a stop motion film because Hugh Jackman or Charlize Theron is in it, but someone got convinced of that somewhere along the line.
No newspaper or chat show is going to interview an unknown voice actor, no parent is going to trust an unknown voice actor won't attach themselves to some offensive rubbish but will trust Tom Hanks.
Celebrities buy you publicity and brand in a way that is hard to replicate elsewhere.
Mirroring what the sibling comment said, studios often spend almost as much on advertising as they do production. I've often heard studios "borrowing" advertising budget to pay named actors for production.
Disney's old plan was to hire past their prime actors. Starting around the 90s when Robin Williams did well for Aladdin, they started courting celebrities who are parents and want to make movies their kids can watch. Also, voice work is considered "easy" (voice actors will fight that connotation). No odd call times, make up, wardrobe, or flying to locations and staying in a hotel (Shrek had Mike Myers record some last-minute dialog inside a limo).
The Disney Renaissance and birth of DreamWorks animated studios during the 1990s and into the early aughts showed that this thinking was backwards and wrong. Commercial and critical success was built upon hiring big name Hollywood actors to lend their voices.
And some of them were exceptionally talented, like Robin Williams or Michael Meyers. Others, like Eddie Murphy, Gilbert Gottfried, Cameron Diaz - they were hired for their voice and their name on the billing. And it worked, it still works, and major productions today don't throw $100 million at a project without stars attached. That'd be crazy.
As a counterpoint I'd argue that these movies are usually also successful in countries where they are screened in non-English. Those voice actors are usually unknown to the general audience (one could argue that they are often the associated voice for the given big name actor but that's not always the case).
At least in Germany, animated movies are rarely advertised as "featuring X" whereas in the U.S. I saw the names of the voices in advertisements.
All of the people you listed have recognizable voices with a history in comedy and they were performing comedy roles in their respective animated films.
Just picking big name actors for a cartoon won't really do much. Everybody knows Tom Cruise by his performances on screen, but people probably won't be throwing down $15 to hear him as a talking donkey like they would with Eddie Murphy.
