Tech's heaviest hitters are speaking out against President Donald Trump's decision to ban transgender people from the US military. 

Trump said in a trio of tweets Wednesday that he would not allow transgender people "to serve in any capacity in the U.S. Military" The decision reverses a still under review policy previously approved by the Defense Department under former President Barack Obama that would let transgender people openly serve in the military.  

Trump's tweets led to backlash from tech execs, many of whom also voiced objections to his immigration ban earlier this year. Facebook CEO Mark Zuckerberg, a frequent Trump critic, said on his personal page, "Everyone should be able to serve their country -- no matter who they are."

Apple CEO Tim Cook tweeted his position along with the hashtag, #LetThemServe."

Google CEO Sundar Pichai, also used that same hashtag, tweeting, "I am grateful to the transgender members of the military for their service."

Not to be outdone, Twitter CEO/co-founder Jack Dorsey, tweeted "discrimination in any form is wrong for all of us."

Trump's transgender tweets are interesting, considering he tweeted last year while running for president that he would fight for the rights of the LGBT community. His tweet came just days after a nightclub shooting in Orlando, Florida, left 49 people dead. Many were from the LGBTQ community.

Meanwhile, Microsoft President Ben Smith tweeted, "We honor and respect all who serve, including the transgender members of our military. #LetThemServe" 

SurveyMonkey CEO Zander Lurie also weighed in with a tweet and the hashtag #transrightsarehumanrights.

And Salesforce CEO Marc Benioff tweeted with an image, "#equalityforall."
