Ookla’s speedtest.net has been the go-to tool to test your network speed for years. They make money by showing you ads next to your speed test.
Google just completely copied their (admittedly simple) product, and put their tool on top of the the search results when you search for speedtest , which makes it appear just above Ookla.
I can not get over the feeling that this is wrong. Google being both a search engine and a tool/content provider leads to this kind of situation where they can cripple existing businesses, and prevent newcomers to compete.
