How much money? 'Making money' doesn't just mean money coming in, it means more money coming in than is going out. Adding features to a product costs money. How many people will buy Windows 10 if it has a good FreeBSD compatibility layer who wouldn't buy it without one? I very much doubt that this is a sufficient number to cover the cost of the engineering work. >> Microsoft, in contrast, is driven by requests from customers who >> spend money on our products and services. >> Around a hundred people >> commented on the WSL issue to add FreeBSD support. > > Ok, do you job and add FBSD support to WSL. First, this is nowhere near even related to my job. I don't work on Windows, let alone WSL. Second, I have already explained why this is not a sufficiently large market to impact engineering decisions. >> If you assume >> that 1% of people who want the feature commented, then this gives >> around 10,000 folks who really want a FreeBSD equivalent of WSL. > > They give money to MS, they ask MS to do job for money. They give money to MS, they get a Windows 10 license in return. They are happy to buy Windows without a FreeBSD compat layer. They are buying Windows on the basis of some subset of a large number of features. The lack of a FreeBSD compat layer is not preventing them from buying Windows, they have not shown that this is the deal-breaker feature. Microsoft, like any other POTS software vendor, will prioritise features that impact the most customers. There are things on User Voice with tens or hundreds of thousands of votes and these tend to be prioritised. Something with under a hundred votes is so niche that it's only going to be a target of investment if it impacts another product or service. >> It's pretty hard to justify a feature in Windows that only 0.001% of >> Windows users will use.

Azure already officially supports FreeBSD and we have contributed a load of code to improve that support over the years. From the numbers I've seen, I strongly suspect that we've spent more on it than we've gained in revenue. You are asking Microsoft to throw money at a thing that will definitely cost time and money (and comes with the associated opportunity cost, because developer time spent on this features is developer time not spent on other features) but with no clear indication that it will increase revenue. Effectively, you are asking us to do work for free and you're also doing so quite rudely. Personally, I'd love to have a FreeBSD compat layer. The license would even make it possible to embed the FreeBSD kernel in Windows and so get the best aspects of WSL1 and WSL2. From a business perspective; however, I can't argue that this would be a great use of engineer time. There are a load of features that would positively impact a lot more users that would be higher priority. If you want this to happen and you want Microsoft to do it, then you need to help people inside the company provide this business case. Things that don't help include: - I want it. - You suck for not doing it. - It would make you money in unspecified ways. Things that do help include: - We are a FreeBSD shop with 1,000 workstations, we would switch to Windows on the desktop with this feature. - We are a large cloud customer with 10,000 VMs deployed, we would switch to Azure with this feature. - We are a Windows shop with a load of desktops but are planning to switch to Macs because we want a BSD-style userland. If you just want it to happen, then you don't need Microsoft to do anything. All of the code required to build a Linux system that integrates with WSL2 is open source and you can implement something compatible for FreeBSD. You can probably even skip a bunch of the boot requirements by using Linux as a bootloader and having a tiny Linux image that just kexecs a FreeBSD kernel. David
