The huge problem with them is that they don't allow creative freedom for movie directors in films like the Marvel Cinematic Universe. This led to the MCU not having much risks taken compared to other comic book films like Deadpool, its sequel, and Joker (despite being a property of Warner Bros. Entertainment and DC).
Not to mention, the MCU is often criticized for being rather formulaic and overstuffed with special effects for the most part. This was more evident after the Disney buyout, in which the films started to take on a more colourful palette and it relies too much on green screens to shoot action scenes.
They also don't allow creative freedom for movie directors in animated films like those in the Disney Animated Canon and those made by Pixar; interesting concepts and stories were wasted that leading to disappointing changes and impressions, infamous examples such as Chicken Little, Cars 2, Frozen 2 (although some of them were included in external source material such as the canon novel
Dangerous Secrets), and Brave.
Quantity over quality: Many modern-day Disney films (primarily the live action studio) only cared about making money than making good quality films themselves, which heavily contradicts Walt Disney's philosophy of focusing more on quality-over-quantity instead of the other way round. According to Walt, he "didn't make movies to make money", instead he "makes money to make movies". The live-action remakes of Disney's classic films are a big example of Disney franchises that are milked to death.
To rub salt into the wound, they shut down not just Avalanche Software, but also Disney Infinity, one of the most beloved games they made, and the reason is that the game "wasn't making enough money", rather than due to the waning popularity of the toys-to-life genre by the time Disney Infinity got
discontinued.
All of their huge company buyouts lead to the idea that they are trying to monopolize the entertainment industry, and it became much more evident after they acquired 20th Century Fox, despite the strong competition posed by other studios, such as rival Warner Bros.
They enforce overly strict conditions upon theatre owners for their films. For example, they demanded higher price cuts for domestic ticket sales for their films.
They also tried to extend the copyright law to the point that the copyright system ended up broken. Various properties like Winnie the Pooh, Alice in Wonderland and Tarzan belong to Disney despite being in the public domain where everyone can use them (and their original authors' family and estates); for example, the infamous Tarzan (2013), in which eventually ruined this reboot of the original film without Disney's involvement as pointed in Saberspark video "The WORST Animated Movies of the Decade Tier List".
They also sometimes rush their films or try to cash in on other parts of their properties like Marvel; this is one of the reasons why their Star Wars trilogy, aka the Sequel trilogy, lacked sufficient planning.
Speaking of which, the Sequel trilogy has become infamous for it's poor writing and lack of planning, communication, and real direction, which all gives the idea that they had the idea for a trilogy first and a story second, and it definitely shows. As the plot and story went from here to there and all of the executive meddling that happened such.
