Open Core and the .NET Foundation: Time for Some Introspection?
As an open-source foundation, the projects you endorse reflect directly on your values, brand, and public trust. Foundations like Apache have set high standards by being selective about projects they host, especially discouraging those that drift into monetization models that reduce openness — such as paywalling core components or shifting key features behind paid licenses.
A current .NET Foundation project, Avalonia, appears to be heading in this direction with its recent move to introduce a paid toolkit called “Accelerate.” - [related thread][1].
While some argue this is a necessary evolution for financial sustainability, it’s worth noting that many high-impact FOSS projects — Linux, Debian, Python, PHP, and Laravel to name a few — have managed to thrive with models that build businesses *around* the software, rather than limiting freedom within it.
If the .NET Foundation seeks to deepen trust within the wider OSS and POSIX communities, it should reflect on whether hosting open-core projects aligns with its long-term vision. A constructive dialogue with Avalonia’s maintainers could lead to a model that supports sustainability *without compromising on openness* — something many in the .NET open source community deeply value.
Open .NET has a bright future, and it’s crucial that decisions today help preserve both the technical and ethical integrity of the ecosystem.
It might be time for the .NET Foundation to initiate a conversation with the Avalonia team and consider offering guidance on sustainable, community-aligned models. Open Source .NET carries high hopes for the future — and allowing short-term monetization decisions to dilute core freedoms risks killing the proverbial hen that lays the golden eggs.

Show HN: I made a blog editor to help me write
I have ideas in my brain but it's hard to write them in articles. GPT helps a lot but the interface/UX isn't great for iterative editing. I used Cursor to build this desktop app(v.0.1) with zero prior knowledge of Rust in 8 days. I really want your feedback. Thanks.

Tell HN: AI is cool, but my apps still suck
I like using ChatGPT and whatever else. It is cool, when it works. I use it for as a coding assistant or a rubber duck, and it adds a good 15-20% productivity boost.
But honestly? Any actual software "tool" that I use on the daily feel like it has just stagnated.
There's AI slop for sure. The "Use AI for..." button is everywhere, and it is kind of a waste for most things.
I don't need AI to come up with a description. I don't need AI to tell me what's already in front of my face. And I also don't need AI to literally make up documentation or hallucinate with half baked information.
Why do the apps I use still load slowly?
Basic functionality is still missing in some of the apps I use, things that have had support tickets open for years and yet zero movement. But there's a AI button or some cutely named AI bot.
Why do exports still break when it is a large data set?
Why do some of these apps look like they have zero UI/UX people working on them? Why are there multiple clicks to get to things that could be done in one click?
Why are there 200 network requests when I load the page?
Seriously, can we stop with the AI/LLM slop and maybe focus on your core competency? I don't need AI jammed into everything. Fire those product managers who think that's a value-add. Maybe talk to your customers?
I just need software that works so I can do my job, and then go and play with ChatGPT and make cool images or come up with a weekend plan.
