We are partly an IT project, which you cannot take away. Also, the 
number and size of imports does not affect how OSM is perceived.

For example, OSMers map very few POIs (relatively), and after they do, 
they update virtually zero of them. Not counting a few active mappers in 
UK and Germany.

To think that you can import everything is to overstate the quantity of 
open data in the world. Open data is mostly points of interest. In some 
countries it's also roads. And that's all. OSM is so much bigger than that.

As for importing POIs, I think that needs to be done, because no mapper 
group would be able to map all fuel station, all Tesco shops, or all 
museums. And if they do, in ten years, but that time half of what 
they've collected will be obsolete. The choice is not between manual 
mapping and importing, it's between importing and not having the data ever.

And since there isn't open data on everything, even if you import all 
POIs you can possibly have in machine-readable format, that will still 
be at most 10% of all POIs, even in UK or Germany. Plenty to map by 
going outside.

So even an army of IT folks armed with data scrapers and contracts with 
every data aggregator would be no match to common mappers, armed with a 
pen and a camera. I fail to see what you're afraid of.
