This week in tech, Elon Musk continues to be a source of controversy and humor. The billionaire CEO of X (formerly known as Twitter) admitted in a deposition that his tweets probably hurt the value of his company, and it was revealed that he roleplays as a toddler on a burner account. Additionally, Musk is facing scrutiny for his refusal to police misinformation on the platform, and has been involved in a war of words with the government of Brazil.

In other news, tens of thousands of LG smart TVs have been found to have software vulnerabilities that could allow cybercriminals to hijack them. It’s important to update your device as soon as possible to avoid being targeted by malicious actors.

X owner Elon Musk has made significant changes to the platform since acquiring it for $44 billion in 2022, including eliminating the word “tweet” and trying to change all references to Twitter.com to X.com without asking users. He has also sold off the company’s famous blue bird memorabilia.

In a 108-page deposition, Musk discussed his strange alternate accounts on the platform, including one where he roleplays as a toddler. The deposition was part of a lawsuit that alleges Musk falsely accused a 22-year-old Jewish man of participating in a Neo-Nazi brawl.

Musk also spent the weekend embroiled in a war of words with the government of Brazil, which has reportedly opened an investigation into his refusal to police misinformation on the platform. He insists that the battle is all about “free speech,” but his history of bowing to authoritarian governments raises questions about his motives.

Other notable stories in tech this week include a video claiming to show a point where the Pacific Ocean meets the North Sea, despite being completely false. Additionally, people have been sharing their concerns about the safety of microwave ovens, and the Federal Aviation Administration is investigating an incident involving a Southwest Airlines flight that was forced to return to its point of origin after the cowling on one of its engines fell off during takeoff.

President Joe Biden is considering a request to stop legal proceedings against Wikileaks co-founder Julian Assange, who’s currently fighting extradition to the US where he faces 18 federal charges related to his publication of secret military documents.

Finally, Dbrand, a maker of skins for mobile devices and faceplates for consoles, got into hot water on social media after making fun of a customer’s last name in a racist way. The company ended up forking over $10,000 to make amends.

VMware Announces Major Change in Licensing Model, Marking the End of Perpetual Licenses

This change affects all VMware products, including vSphere Standard and VMware vSphere Essentials Plus, which will still be available for small deployments and environments with limited requirements. To soften the transition, Broadcom is preparing measures to encourage businesses with perpetual licenses to switch to subscription-based offers with attractive pricing incentives.

Going forward, VMware will offer two main offers: VMware Cloud Foundation and VMware vSphere Foundation. These new licenses are the culmination of a two-year journey undertaken by VMware to simplify its portfolio and transition from a perpetual model to a subscription-based model to better serve customers with continuous innovation, faster time to profitability, and predictable investments.

According to VMware by Broadcom, this change is the natural evolution of the company’s licensing model, and it marks the beginning of a new era for VMware and its clients. The company believes that this shift will enable it to better serve its customers with a more flexible and cost-effective model that provides access to the latest technology and innovation.

In conclusion, the discontinuation of perpetual licenses by VMware represents a significant change in the company’s licensing model. This move is part of a larger effort by Broadcom to simplify VMware’s portfolio and transition to a subscription-based model. While it may be challenging for some customers to adapt to this new reality, the benefits of this shift are undeniable, and it marks the beginning of a new era for VMware and its clients.
