I‘ll probably get downvoted for this, but big companies do not ruin everything for profit. Google Calendar, for example, is a simple tool which is very well implemented on various systems and it just works. And if you want more privacy, then you can go to Proton Calendar.
Also a typical argument is made that more should be done against anti-competitive behaviour. The problem is that there is no better alternative. If you regulate competition too much then people will not spend their time and/or money on moonshot ideas anymore. Why take a massive amount of risk if you aren’t allowed to reap the rewards? This is what happened in the Soviet Union and nowadays partially in China. Innovation stalls and all you can do is copy. Russia, for example, tried to make chips by copying the American designs, but without understanding the fundamentals. Unsurprisingly, it didn’t work.
So complete regulation for anti-competitive behaviour doesn’t work. Then governments should probably just regulate a little bit? This is precisely what the US is doing. Yes, sometimes corporations push it too far and consumers are negatively affected. However, the alternative is less innovation which will also negatively affect customers.
For the counterargument that technology doesn’t make things better. (Even this is nowadays a common argument.) Compare living today with living in the 1980s. Transportation, education, medical aid, and entertainment are in general much better. Yes, there are some negative sides, but I wouldn’t want to be born 40 years earlier. Having to write letters to your family when they are overseas. No YouTube. Internet measured in kB/s. Sending patches via email on repositories without CI/CD. No thanks.
