Sort of, inconsistently. Bill Gates' "An Open Letter to Hobbyists" was finger-wagging about rampant pirating of Altair BASIC in 1976 was a thing. The fight evolved into multiple generations of copy protection and cracking/copy defeat measures, SPA "shareware" crippleware, and Nancy Reagan-like "Don't Copy That Floppy". Personal-use pirating was rampant. Heck, when I worked at Egghead Software, the store manager's unofficial was anything that was shrinkwrapped but not envelope license sealed could be borrowed, taken home, and brought back. There wasn't much point in violating that generous policy because not for resale (NFR) full copies of the expensive stuff were available from the vendor representatives (Microsoft, Borland, Corel) for between $1 and $50 (USD). I think Borland C/C++ 3.1, the largest and heaviest shrinkwrapped software package with books ever made, was probably NFR $70.
