"For the most part probably because now Sony treats PSNow as their answer to Microsoft B/C program"
I think you have your timeline mixed up. PS Now was created to preserve the PS3 legacy software since the cell processor made it difficult to emulate. The PS2 and PS3 were both backwards compatible but the changes in technology, business models, and the cell made it difficult for the PS4 to run PS3 games including the PS2 classics purchased on the PS3 store. PS2 was a disk only console. PS Now was Sony's way of future proofing as well as offering a Netflix style rental service. Sony was going to evolve the PS Now service over time. They were always going to add PS4 games because PS3 games are not enough to keep the service growing.
Xbox One was not backwards compatible with Xbox 360 in the beginning and Microsoft had no intentions of adding the feature. It wasn't until PS Now launched and Xbox One started losing in sales that Microsoft started working on Xbox 360 BC.
"I can't really quite remember journalists cheering for Microsoft this gen at all.They supported Sony way more."
Well, I don't know what to tell you because that is not the history I've seen. Journalists have been defending the Xbox One since it launched. For the most part they give Microsoft a pass on most things other than the things that they can't hide such as the exclusives issue. They hype up almost everything Microsoft does. The last year has basically been an anti-Sony campaign because Sony didn't want to open the gates to Nintendo and Microsoft. Microsoft received passes over the past 13 years for blocking cross play with PC.
News journalists are not the reason why the PS4 is winning or the reason why Microsoft is making changes. Many journalists owned both since the beginning of the generation. The reason why the PS4 is so far ahead and why Microsoft is making changes is because of the general consumer (majority of gamers) who purchase PS4's but refuse to purchase Xbox Ones. I think if the journalists had their way and if their narratives started influencing the general consumer the Xbox One would've sold better, Microsoft would have never changed, and we would be in trouble.
"Sony should have made possible to stream Remote Play by local network. At least it really seems that it can't do that from my experience."
You can already do that with Remote Play.
"With all the latencies and poor image quality that Remote Play gives you when you use it at home, it really looks like they still use their servers to stream for some reason. So, yeah, if we talk about streaming to home PC, Microsoft solution works better."
That has not been my experience. Many Xbox One games are only 900p or 720p. The image quality varries based on your home connection, what device you use, streaming resolution, and other factors.
