Apple moved first to stop showing results for his podcasts - save one - from appearing in the iTunes library, then Facebook and YouTube made a decision to remove the main InfoWars pages from their sites.
In a statement, a YouTube spokesperson said the company removes accounts that repeatedly violate its policies.
"Upon review, we have taken it down for glorifying violence ... and using dehumanizing language to describe people who are transgender, Muslims and immigrants, which violates our hate speech policies", said Facebook.
In the latest clash between big tech companies and those who hold unpopular or controversial views, Facebook has permanently kicked "Infowars" off of its platform, saying the page was "unpublished for using hate speech".
Facebook's removal of Jones' pages follows criticism of CEO Mark Zuckerberg's interview with Recode in July. On Monday, Spotify also told PCMag it had banned Alex Jones from the platform over repeated violations relating to hate speech. The source said Jones received a 90-day moratorium on livestreaming for violating its policies, and that he then tried to promote his livestreams on other YouTube sites, prompting a permanent ban.
Still, the decisions by Apple, Spotify and Facebook may clear the way for other platforms to take action, now that a precedent has been established. Also on Monday, the entirety of hundreds of episodes of "The Alex Jones Show" had been removed from music streaming service Spotify. Facebook followed suit, taking down four of Jones's most popular pages and effectively banning him from the site.
After learning of Jones' banishment from Facebook in a Mashable article, Cruz seemingly came to Jones' defense on Twitter - even questioning the social media giant's authority on blocking free speech.

"Infowars is not "press" & Alex Jones is not a journalist", Reilly wrote.
"Podcasts that violate these guidelines are removed from our directory making them no longer searchable or available for download or streaming", Apple said in a statement.
Embattled conspiracy theory broadcaster Alex Jones was banned by YouTube on Monday.
Jones has repeatedly spread the false claim that the deadly 2012 shooting at Sandy Hook Elementary School that killed 27 people was a hoax. "I can confirm that Spotify has removed the "Alex Jones Show" - Infowars", a spokeswoman said.
"(It's) a risky cliff that these social media companies are jumping off to satisfy CNN and other liberal outlets", Bozell said in a statement.
