Microsoft blocks Tutanota users from own service: Tutanota users can't register a Microsoft Teams account and Microsoft won't change this.

This demonstrates why stronger antitrust legislation is badly needed.

Politicians on both sides of the Atlantic are discussing stronger antitrust legislation to regulate Big Tech. These laws are badly needed as the example of Microsoft blocking Tutanota users from registering a Teams account demonstrates. The problem: Big Tech companies have the market power to harm smaller competitors with some very easy steps like refusing smaller companies’ customers from using their own services.

Currently, Microsoft is actively blocking Tutanota email addresses from registering a Microsoft Teams account. This severe anti-competitive practice forces our customers to register a second email address – possibly one from Microsoft themselves – to create a Teams account.

When asked to change the current situation, a spokesperson for Microsoft simply said it would not be possible for them to allow people to register a Teams account with a Tutanota email address. Period. We repeatedly tried to solve the issue with Microsoft, but unfortunately our request was ignored.

This is just one example of how Microsoft can and does abuse its dominant market position to harm competitors, which in turn also harms consumers.

The last successful antitrust case in tech happened in 1995 against Microsoft. At the time, Microsoft was one of the biggest tech companies as almost every computer was running Microsoft Windows. Back in the nineties Microsoft bundled their Internet Explorer browser into Windows OS so that every computer being sold also came with their built-in browser.

The case United States vs. Microsoft made the news back then. Microsoft lost the case and was no longer allowed to bundle the Windows operating system with the Internet Explorer.

Weakening Microsoft paved the way for a period of technological innovation. Following this successful antitrust case new tech companies emerged that have since adopted the practice of abusing their market power to stifle competition themselves: Google, Facebook, Amazon, and Apple.

Free isn’t free

At first glance, the deal consumers get from Big Tech is very beneficial, after all they can use the product for free. However, targeted advertisement also makes people pay.

By knowing consumers so well, Big Tech can place ads at the right moment and at the right price. For every major turn in life, the appropriate ad will appear. Say, you are invited to a baby shower. Ultimately you will be bombarded with ads for baby’s clothes and toys, but maybe a handmade gift would be much more suitable?

Consumers will lose the ability to make free and independent decisions due to the never-ending presence of advertisements and their influence.

The aim of Big Tech is to make you spend money – and they are very successful with that.

Privacy is needed

In recent years the demand for privacy is constantly rising. Big Tech companies such as Microsoft can not easily deliver this as a large part of their business relies on the profits made from targeted advertisements – and for that they need to track their users.

“We need to break up the market power of Big Tech like we did in the nineties. This will lead to a new evolution in today’s online world. One where products rise that concentrate on benefiting the consumer – not maximizing ad revenue”, says Pfau. “To free oneself from being tracked online, people need privacy-respecting alternatives. We have built a fully encrypted email service – Tutanota. We respect people’s privacy and protect their private emails from malicious attacks, prying eyes, and ad-based tracking. Due to the built-in encryption, tracking is impossible in Tutanota."

"However, competing with Microsoft is nigh impossible given their sheer market power."
