Couple of suggestions: Oracle's OCI has a free offering. One could use that as a mail relay.
Also SpamHero has been a pleasure to work with with very reasonable pricing to filter most of the junk that comes in, re-delivery service and outbound relay
Let's not forget that these policies fostered the development of encryption in Canada, Australia and other countries (See SSLEay for example).
So it ended up being counter-productive.
The simplest way to stop competition is to subsidize a product. In this case, offer the tools openly.
There are lots of systems that don't support ACME. Enterprise firewalls for example are just starting to support it. Lots of embedded devices still do not support it. Older enterprise servers have either very poor or not compatible enough to make it work reliably.
Sometimes in 2016 we were working on a kitchen renovation and decided on a built-in double oven, and went with GE's offering. I seriously considered $ 300 more for the top-shelf offering that included convection on both ovens and Wi-Fi connectivity.
Back then Haier just bought GE Appliances and that made me waver. Also I knew their fridges with Wi-Fi were running Windows CE, what I didn't think it would have a long future, and integration through a now chinese/american company didn't quite appeal me.
In the end bought the version without Wi-Fi and only one convection oven, which has proven more than enough.
The advantage of Wi-Fi we though would be to be able to set the oven to cook the food left on it by the time we arrived from work.
But then again food had to be left at room temperature most of the day, so we figured it wouldn't be something we would use too often.
Now after two years of working from home, this became more irrelevant.
Now my house is as automated as I can possibly make it, but running local mesh networks (Z-Wave and Zigbee), and the few Wi-Fi devices are HomeKit enabled, which means it should not depend on 3rd party cloud offerings for standard functionality, and has been mostly limited to decorative lighting developed in North American or European companies.
When I had a 2016 Mazda, I regularly downloaded their firmware, which at some point came fairly frequently.
Like other manufacturers, their dealer portal posts firmware upgrades along with other service bulletins, and occasionally the firmware leaks out from some of their dealers, so enthusiast would go on upgrade it by themselves.
The 5G twist is pure BS. These cars (Circa 2016) have no modem that connects directly to the head-unit, and if they do are a separate module that's 3G only.
My theory is that the radio station sent some unicode characters on their RDS feed that crashes the system, it probably cached it (These head-units run on Linux, and is well known in some hacker circles), so now it's in some kind of loop.
It won't be the first time that RDS feeds with some unusual combinations crash the head-units.
If Mazda has a new firmware, these can be upgraded via the USB ports by booting into a recovery mode.
I had Surface 3 Pro and it was a nightmare. In the end, the SSD died and the way the machine is glued together, it's impossible to open without breaking the screen.
Before its final death, it had problems with sleep/wake functions. A standard reinstall wouldn't fix it. Eventually had to take it back to Microsoft for a full re-image. That did the trick.
There is minimal effort in a CLI app compared to a full-fledged web app.
I also appreciate how much faster things are when there is a CLI REST APP instead of a GUI front-end for the same application.
