Jack Dorsey, co-founder and former CEO of Twitter, commented on Elon Musk's decision to set viewing limits on some tweets.

Dorsey said that running Twitter is hard and there is no easy answer to balancing free speech with preventing harmful content.

He believes Musk is the right person to lead Twitter but is still concerned about the company's future under his ownership.

Musk's decision to set viewing limits has been met with criticism from some users who argue it is censorship.

Musk has defended his decision, saying it is necessary to protect users from harmful content.

The controversy surrounding Musk's decision is just the latest in a series of challenges Twitter has faced in recent years.

The company has been criticized for its handling of misinformation and hate speech, and it has also struggled to grow its user base.

Musk's purchase of Twitter has raised hopes that he will be able to turn the company around, but it remains to be seen whether he will be successful.

 Dorsey believes Twitter is at its best when it is free and open, but acknowledges it is a complex platform with no easy answers.
