Downloading apps off app stores is easy. These sketchy websites can actually be real useful when developers decide to geolock their apps (i.e. when a local ride sharing app won’t download because your Google account isn’t from the country you’re visiting). apkmirror has also helped me obtain various Google apps that didn’t come with my phone’s custom ROM, though that’s one of the good ones that doesn’t alter apps.
Many of the sketchier will take apps and alter it to inject malware, though. By removing in-app purchases/ads/DRM with tools like lucky patcher they can explain away why people’s phones are calling these apps malware (because the alterations are to be expected), but the goal was never to give people free stuff, there’s always money behind it.
Corporate wants people to port their COBOL code into Java 8.
Most of them have decided on a tech tech a decade ago and they’re not going to change anything about it unless they absolutely have to, whether that’s Java or C# or Python or Ruby…
Rust is gaining traction, but mostly for new projects or big revamps, and there’s a lot more shitty old code to maintain than there are opportunities to develop anything new. Besides, most companies don’t need Rust (or C or C++ for that matter), JVM/.NET/NodeJS/Go is fast enough for even intense corporate workloads and doesn’t require people to put in the effort to make everything perfectly sound.
