We are still dealing with stupid Google issues like any time our mail relay sends mail to Gmail servers it's 50/50 whether they decide to block it saying we aren't authenticated properly even though our SPF record is indeed valid.
Tell that to Comcast.
Google has alternatives on all their services except arguably YouTube and search
YouTube is uncontested. Let me throw in a couple of others: for desktop maps, AFAIK Google is still tops (on my phone I use Apple Maps and it's...fine). For free email, AFAIK GMail is still the standard (despite various UI changes over the years that have made it worse).
It survives solely on network effect. I can't wait for a competitor, and several are waiting in the wing.
I use Apple Maps on desktop as well. In my area (Denver) they seem to have about the same number of unique issues, but
1. Mobile Google Maps is so, so terrible in terms of screen-space utilization, look and feel, and also its behavior doing turn-by-turn. I've never been anywhere close to as angry at my iPhone then when Google Maps confused me into a parking lot and the low-quality synthetic voice got nearly a minute behind in micromanaging my way out
2. Desktop Google Maps is a lot less usable if you refuse to give the entirety of Google.com precise location access. The move from maps.google.com -> google.com/maps marked the last time I asked it for directions.
However, I'll also say that sometimes the alternatives to Google aren't very good, though they do of course exist. Anything that requires an Apple device is a no-go for me, for instance, so things like Apple Maps are out. Google Maps for me is a must-have, for instance; I use it for navigating Tokyo on a daily basis and something like OsmAnd isn't going to work here at all (Google Maps finds businesses, tells me when they're open, and tells me exactly how to get there on public transit.) Google Docs is pretty useful for some things too; I don't use it for anything too important (I use LibroOffice at home for that), but for something I want to be able to access from my phone or work computer, it's great. The competition seems to be MS Office 365, and I'm not going to use that: I hate MS and I see no reason to pay for a subscription service here when Google's free offering is fine. Google Calendar is really useful too, and lets me share my calendar with others easily.
Comcast is truly evil and horrible, but since the US loves monopolies and lets companies like Comcast establish local/regional monopolies, people there are stuck with them. In better-run countries like where I now live, this doesn't happen, because there's tons of competition for internet service.
YouTube really is pretty close to a monopoly though; it's not like you can just go to Vimeo and find the same videos.
Supply side economics says this is what we supply, you buy. Thats how it works.
To be honest, I have gotten pretty good support from GSuite, though it was fixing Google's own incompetence. It turns out that if you bought GSuite when prompted while registering your business' domain w/ Google Domains, that was a special GSuite locked out of certain features. Because reasons. It took contacting support to fix this. In a very Googley way, it was clear that many companies had hit this problem, and they'd built tools to fix it. They of course didn't stop the problem, but they did have a well-orchestrated process to fix it...
