If you are in expansion mode (like AWS), your overheads are likely to be and are justifiably high.

Neither do you want a tax burden during your expansion phase which a profit will create.

This strategy enables quicker business growth and greater eventual profitability with minimised tax.

Thus increasing revenues can be a more reliable indicator than profit that all is going according to plan.
