TYOTLD means that when you say "how do I run the standard tools that anyone doing what I am doing uses", you are just pointed to where to install them. If you are pointed to a free, open-source tool, it is because that is what everyone uses now because it beat out any paid, closed-source alternatives.
TYOTLD means that Microsoft's office suite runs on Linux, or that MS Office has been replaced by something that does across the entire world of office work.
TYOTLD means that all of Adobe's tools runs on Linux, or have been replaced by something that does across the entire creative industry.
TYOTLD means Linux won and Microsoft and Apple are both bit players.
If you are preparing a reply about how long it's been TYOTLD for you: great! You've been living in the future! But like Gibson said, the future may be here for you but it's not evenly distributed.
Do you want it to be more evenly distributed? Then when people tell you why it's not here for them, listen to them instead of dismissing "all these new problems we've just thought about", and put some effort into helping to solve some of them. Polish up those compatibility layers to make it easy to run things written for Windows. Improve the open-source tools aiming at replacing the commercial ones. Help create and fund advertising campaigns, help figure out how to pay the people doing all of these things for their time and expertise.
