The rowlatt act of 1919 was very unpopular with the indian people because it

controlling and silencing the press

arresting people who might be committing treason

imprisoning political activists

hope it helps

freedom of speech is also protected by the 1 amendment.

explanation:

here is pretty much what the 1st amendment says:

congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.
