No, the World Wide Web Isn't Open (and Hasn't Been for Years)
It's proprietary all the way now
At risk of becoming or at least sounding way too repetitive, today's "modern" Web browsers are all proprietary. If you truly reject proprietary browsers, there will be many sites that will reject you and tell you to go away (or come back with a proprietary browser). Oh, hi, Evri.
This is really bad. Really bad. This is what it's like in Asia this month:
The most likely explanation for this tiny anomaly is that little Armenia just has too small a dataset for statCounter to accurately gauge/survey user agents (UAs).
The Web is proprietary. Remember to tell that to people. Yes, there are some specifications out there, but unless one adopts proprietary software, many sites will remain inaccessible, unusable etc. This will only get worse over time. What's not truly proprietary is OSPS [1, 2]. Even the OSPS isn't good enough anymore; there are now important Web sites, including government and commerce sites, that won't work with anything but Google Chrome.
We shall continue to remind readers that we have full, analogous presence in Geminispace. Ideally more sites will port over to it. The Open Web isn't coming back, ever. The World Wide Web Consortium is thoroughly compromised. █
