Silicon Valley may finally extend a peace offering to Donald Trump at Wednesday's technology roundtable, but it's been a rocky road for both parties since the election.

Some of the region's top tech executives openly denounced the President-elect, while others lobbed more targeted criticisms and consequently landed in the crosshairs of a Twitter rant from Trump himself. 

In announcing the final list of 12 attendees on Wednesday morning, Trump spokesperson Sean Spicer acknowledged that "a lot of these folks were not very supportive of [Trump]."

Attendees are likely to look past those differences, however, in favor of advocating for the issues most important to Silicon Valley, including immigration, corporate tax laws and international trade, among other things. 

Several leaders may find it a bit harder to strike a conciliatory tone with Trump, however, thanks to comments they made during his bid for the White House. 

Here's a list of some of the notable, if not nastiest, words traded between Silicon Valley leaders and Trump: 

1.  Amazon (AMZN) - Get Amazon.com, Inc. Report CEO Jeff Bezos suggested last December that Trump should be sent into space, following a series of tweets from Trump that said Amazon was using  The Washington Post as a tax shelter for the e-commerce company. Bezos bought The Post in 2013.

2.  Facebook (FB) - Get Facebook, Inc. Class A Report  COO Sheryl Sandberg will be representing the social networking giant at Wednesday's roundtable, but its CEO Mark Zuckerberg issued a dig at Trump on the issue of immigration. At Facebook's F8 conference in April, Zuckerberg warned of the dangers of cultivating a culture of fear in the U.S., which many listeners deduced as being aimed at Trump. 

"I hear fearful voices calling for building walls and distancing people they label as others," Zuckerberg said. 

3. Tesla Motors (TSLA) - Get Tesla Inc Report CEO Elon Musk, who was added to Trump's financial advisory council on Wednesday morning, said in November said the election wasn't "the finest moment" in America's democracy and went on to say that he disliked Trump.

"I feel a bit stronger that he is not the right guy," Musk toldCNBC. "He doesn't seem to have the sort of character that reflects well on the United States."

4. It's unclear whether Hewlett Packard Enterprise (HPE) - Get Hewlett Packard Enterprise Co. (HPE) Report  CEO and one-time California gubernatorial candidate Meg Whitman was even invited to the tech roundtable, but she surely voiced her opposition to Trump during the election season.

In August, she called Trump a "dishonest demagogue" who could steer the country on a "very dangerous journey." She also pledged her support for Trump's Democratic rival Hillary Clinton. 

To be sure, one of Trump's most notable supporters in Silicon Valley has been early Facebook investor and billionaire Peter Thiel, who now's a key transition official for Trump's administration and the organizer of Wednesday's event. In an October speech at the National Press Club in Washington D.C., Thiel offered this positive assessment of Trump:

"No matter what happens in this election, what Trump represents isn't crazy and it's not going away. He points toward a new Republican Party beyond the dogmas of Reaganism. He points even beyond the remaking of one party to a new American politics that overcomes denial, rejects bubble thinking and reckons with reality."
