To take a simple example under Section 174 rules let's take a bootstrapped business with one US-based developer developing a SaaS product. If you pay them $100K and also bring in $100K revenue, prior to Section 174 the taxable revenue was 0. Under section 174 the business now can only claim $20K and the taxable revenue is $80K. Your tax bill is some fraction of that after you get done applying credits of various sorts.
The problem with the Section 174 change is 2-fold. It was unexpected--most people assumed it would be corrected. It also hits bootstrapped businesses hardest, which are exactly the sort of businesses we should be encouraging. VC-backed businesses have less of a problem early on because their expenses tend to be so high that even with Section 174 they aren't profitable. However even there as a founder there can be a substantial impact, because the Section 174 charges eat up your Net Operating Losses (NOLs) which you can use to offset the profit from selling the company or future tax bills.
Edit: as others have pointed out the amortization schedule is apparently not linear, so 20% might not be right. The other complication is that there are many deductions and adjustments that affect your taxable revenue. NOLs are the biggest in my experience but there are others.
