Reducing ad spend on one platform, albeit often the elephant in the room for most companies’ online marketing department, isn’t going to reduce prices at the till. Companies will either reallocate the ad spend elsewhere, there by spamming more ads in front of everyone, or pocket the difference to pad their profit margin.
Google did not make RCS; RCS is made by GSM consortium as succession of SMS, Google extended it to add some extra features such as end to end encryption (but only when messages are routed through their servers).
China mandated 5G sold in China must support RCS, hence why Apple added support for this. Since Google is basically banned in China, you can pretty much bet RCS going into/out of China is going to be unencrypted.
So you’re basically stuck between getting inferior unencrypted messages, or routing everything through Google.
Avoid RCS like the plague.
Not entirely true… the American Android users care about it; Apple users will still default to the superior iMessage as opposed to the inconsistent carrier dependant RCS; rest of the world will use geo-preferred third party messaging app that also offer consistent experience between carriers.
“Buy your mom an iPhone” people.
4o does perform web searches, give summaries from a couple of pages, and include the link to those pages when prompted properly.
However, as most people know, first couple results doesn’t always tell the full picture and further actual researches are required… but, most “AI assistant” (also including things like those voice assistants in speakers) users tends to take the first response as fact…
¯\_(ツ)_/¯
