I believe it's because they are not made available for download as a csv
file.
Compare:
https://www.google.com/finance/historical?q=NSE:TCS
with
https://www.google.com/finance/historical?q=NASDAQ:AAPL
You'll see that for AAPL, there is an option to export prices on the
right hand side: that's what getSymbol() takes advantage of.
Why it exists I don't know, but it probably has to do with how much
google is willing to pay for licensing to foreign exchanges.
You could perhaps write something to read the price table that google
shows or if you find the data available elsewhere on a csv, I'm sure
the package authors would be willing to add another method for
getSymbols.
