It seems Musk hasn't forgotten, as evidenced by a recent dig at Bezos. </p><p><a href="https://www.washingtonpost.com/technology/2021/02/23/musk-tesla-texas/">The Washington Post's Faiz Siddiqui</a> published a report on Tuesday about how the demands on Musk's timeincluding his travel schedule, <a href="https://www.businessinsider.com/elon-musk-girlfriend-grimes-relationship-photos-2018-8">personal life</a>, and focus on SpaceX, the rocket company he also runsare beginning to impact Tesla, leading to what some critics view as missteps in his management of the business. </p><p>While reporting the story, which The Post said features interviews with a dozen current and former Tesla employees, investors, and analysts, the publication reached out to Musk by email and received a brief response in return. </p><p>"Give my regards to your puppet master," Musk said in response to The Post's request for comment. </p><p>The comment appears to be in reference to <a href="https://www.businessinsider.com/washington-post-insiders-speculate-jeff-bezos-plans-2021-2'r=ah-sub">Bezos' ownership of The Post</a>he bought the paper in 2013 <a href="https://www.washingtonpost.com/national/washington-post-to-be-sold-to-jeff-bezos/2013/08/05/ca537c9e-fe0c-11e2-9711-3708310f6f4d_story.html">for $250 million in cash</a>. Both Bezos and The Post have said repeatedly that the Amazon CEO has no influence on The Post's editorial decisions.</p><p>But that hasn't stopped critics from conflating the billionaire tech founder and the nearly 150-year-old publication, most vocal among them former President Donald Trump.

Over the last 15 years, Musk has leveled a string of criticisms at Bezos and his rocket company, Blue Origin, including calling Bezos a copycat over some of his business ventures, describing Amazon as a monopoly, and appearing to make some digs about Bezos' age.</p><p>For his part, Bezos has repeatedly critiqued SpaceX and Musk's main goal, which is to send humans to MarsBezos has described the idea as "un-motivating."</p><p>"Go live on the top of Mount Everest for a year first and see if you like it, because it's a garden paradise compared to Mars," Bezos <a href="https://www.businessinsider.com/jeff-bezos-mount-everest-challenge-mars-spacex-elon-musk-2019-3" data-analytics-module="body_link" data-analytics-post-depth="60" data-uri="42bddd219157167de6f62d40e69c1a41">said in 2019</a>.</p><p><a href="https://www.businessinsider.com/elon-musk-jeff-bezos-dig-washington-post-ownership-2021-2#comments">Join the conversation about this story »</a></p> <p>NOW WATCH: <a href="https://www.businessinsider.com/literacy-test-louisiana-disenfranchise-black-vote-2016-6">We took a 1964 Louisiana literacy test and failed spectacularly</a></p> Click here to read full news..
