Since January, entrepreneurs from across America have fought hard against President Trump's travel ban, which prohibited citizens from six predominantly Muslim countries from entering the U.S. On Monday, those business leaders took a heavy blow and some spent the day licking their wounds instead of speaking up.

The Supreme Court allowed parts of Trump's ban to go into effect until it ultimately decides the case in October, but the justices said the ban does not apply to non-citizens who have formal relationships with people or entities in the U.S. While it appears companies can still hire workers from the affected countries to work in the U.S., some members of Silicon Valley spoke out against allowing any part of the ban to stand.

Kickstarter, which was among 160 technology companies that told a federal court in Virginia to block Trump's travel ban in April, was one of the first firms to weigh in on the ruling. "Allowing parts of the ban to go into effect with respect to some immigrants and refugees is disappointing," Michal Rosenn, general counsel at Kickstarter, said in a statement provided to CNN Tech. "It will have a negative impact on America's standing in the world, and on companies' ability to recruit and retain the best talent."

But other prominent entrepreneurs and Silicon Valley heavyweights weren't as quick to share dissatisfaction, and if they did, they're message wasn't clear. Mark Zuckerberg shared a photo of latte art Monday afternoon, but didn't offer any thoughts to accompany the subtle imagery. Facebook was one of the companies to file a brief with the U.S. District Court of Appeals for the Fourth Circuit in April.
